• Virtual Machine Network Services causes networking problems in Vista Enterprise 64 bit install

  - by Bill

  I have a Quad-core/8GB Vista Enterprise 64-bit (SP2) installation on which I installed Virtual PC 2007. I have a problem that is opposite of all that I found searching around the Internet--everybody has problems making network connections from their guest VM. When Virtual Machine Network Services is enabled in the protocol stack for my network card across a reboot, it causes access problems to the network. The amount of time to login in using a domain credentialed account is upwards of 3 minutes, then after reaching the desktop the network and sharing center shows that my connection to the domain is unauthenticated. Disabling and re-enabling the Virtual Machine Network Services (uncheck in network properties/apply/recheck/apply) fixes the problem. And as long as I have the VMNS disabled when I shutdown the restart runs smoothly. I just have to remember to enable after login and disable before shutdown. I have un-installed and re-installed Virtual PC 2007 multiple times with restarts between. The install consists of the SP1 + a KB patch for guest resolution fix. Any help would be greatly appreciated. Some additional information... At one point during my hairpulling and teethgnashing with this, I tried to ping my primary DC and observed some weird responses: (Our DC is 10.10.10.25, my dynamic IP was 10.10.10.203) Reply from 10.10.10.203, Destination host unreachable. Request timed out. Reply from 10.10.10.25: ... This is not consistently repeatable, but thought it might strike a chord with someone.

• Windows 7 starts getting sluggish over a few days

  - by munrobasher

  Myself and the other developer are running Windows 7 Enterprise 64 bit with 8GB RAM on different Gigabyte motherboards with Quad core Intel CPUs. Most of the time, it runs like a dream. We use VMware workstation a lot (hence the 8GB) and that works well. Except... now and then, after the PCs have been on for a few days, the whole system starts getting really sluggish doing certain tasks. The other's developer's system is far worse than mine with it taking up to a minute to launch IE. Today, mine has gone sluggish but nowhere near as bad. For example, normally when I click on a new tab in IE, it's instant. Today, there's an obvious delay. Right-clicking in this window to trigger iSpell is normally instant, right now it takes about five seconds. I've got resource monitor open on my second monitor and when I did that right-click, there was no obvious peak in CPU, disk or memory. A reboot does fix it so it does sound like a resource issue but haven't a clue what might be to blame. The two computers have similarities (same spec) but also differences (like motherboard, RAM & CPU models). So I guess the question is, any pointers on diagnosing why a PC is sluggish? What could cause such a right-click slow down in IE for example? It sounds like such a simple operation. NOTE: whilst typing this message alone, it was fine performance wise. I can click around the page no problem but right-click still is noticeable slow. Will reboot over lunch... Cheers, Rob.

• Load is 0, yet site crawls (sometimes). What gives?

  - by Yegor

  I have a ~1.5-2mil page views per day site running on 2 servers. One for mysql, other for everything else. Mysql box has a load of 3, frontend is usually 0.0-0.1. Both are dual quad core with 8GB ram running SAS drives in raid5. CPU is idle for majority of the time, iowait is non-existent. Im running nginx, memcache, and site is built on php. Half the time everything runs perfect, while at other times it lags something severe, when it takes 10-15 seconds for a page to load. Page execution time is always super low, but it seems to hang, waiting for something before it actually loads the page. Whats even more weird is that it only happens to 1 file on the site (but its the one thats most commonly accessed, that actually loads the content on the site). Other pages are super fast at all times, even when it takes 15 seconds to load actual content. I have nginx_stats plugin installed, and if I monitor it, the lag spikes happen when the write column starts going above 100, and it frequently does... all the way to 500-1000. It does so at totally random times... not when traffic is heavy... it can do this in the middle of the night, and work perfectly at 5pm when traffic is at its highest. Any ideas?

• Performance tweaks and upgrades for VMWare Server 2

  - by sjohnston

  Our software department has a server running VMWare Server 2. We typically have 8-10 VMs running as test environments (Win XP and Server 08) for various versions of our software, and one VM that is used as a build server (Win XP). The host is running Server 2003 R2. It has 32GB RAM, 8 core Xeon 3.16GHz CPU, one disk for host OS and two raid disks for VMs. The majority of the time, this setup behaves very well and there are no complaints. Other times, the VMs can be very laggy. This is sometimes, but not always, correlated to heavy load on the build server. I'm a software developer, not an IT pro, but it seems to me that this machine should be beefy enough to handle this many VMs. Is this occasional performance hit likely just because we're hitting the limits of the hardware, or should I be looking for another culprit? From what I've read, I'm guessing if there's a bottleneck, it's probably disk I/O with all these VMs running off two disks (especially the build server). Would spreading the VMs over more disks, and/or switching to SSDs give us a significant performance boost? Other things I've read may increase performance: single virtual processor per VM removing/disabling unused virtual hardware preallocated disk space not using snapshots setting a reserved memory limit on the host and disabling VM memory swapping Can anyone confirm or deny if any of these improve performance? What other good tweaks have I missed?

• Why is dwm.exe using so much memory?

  - by Leonard Challis

  I've scoured the web, but I'm sick of reading "scan your computer for viruses" and "upgrade your RAM" on answers to similar questions to this. I understand that dwm.exe is for (simply put) caching bitmaps for things like Aero-peek and similar, but as far as I have read it shouldn't be using vast amounts of memory. My colleague and I both have 4GB of RAM, Core 2 Duo, blah, blah -- essentially they're pretty capable. His dwm.exe is running at around 30mb, mind is currently running at about half a gig, though it does fluctuate quite a lot. This is the same while running the exact same applications (currently Zend studio, FireFox (with firemin - low memory usage), Outlook). Every so often I will get a notification asking me if I want to switch to Aero Basic because it's using too much memory, and sometimes it will just switch itself to basic and let me know why. I know it's possible to stop it switching, but I want to know why it is using too much memory otherwise it's just papering over the cracks. One thing to add is this seems to have started after a robbery on Monday, where two of my monitors were stolen, and I had to temporarily use a couple of alternative monitors. I am now using brand new monitors but the problem is the same. All drivers installed and working seemingly fine. Any ideas why the usage is so high? We are using windows 7 64-bit Professional.

• Windows Server 2008 R2 running at a snail's pace

  - by Django Reinhardt

  Really weird problem here. Our main web server has started running at a snail's pace, for absolutely no reason we can discern. Even after restarting the machine, when there's no little or no ram usage and CPU usage is fluctuating between 0 and 30%, simple tasks, like opening Internet Explorer, or waiting for My Computer to open, take forever. There are no processes hogging system resources that we can see... the machine itself is just exhibiting extremely slow behaviour. I've never seen a machine do this. A lot of security updates had built up, so we decided to let Windows install them. When we looked through the history upon restarting, though, they had failed with error code 800706BA. I don't know if this could be related or not. Any help in this matter would be greatly appreciated. As mentioned in the title, we're running a Windows Server 2008 R2 machine. It's also running SQL Server and IIS. It has 16GB of RAM and a decent Quad Core processor. It's also been fine until now -- and we haven't changed a thing. Thanks for any help.

• SQL Server performance on VSphere 4.0

  - by Charles

  We are having a performance issue that we cannot explain with our VMWare environment and I am hoping someone here may be able to help. We have a web application that uses a databases backend. We have an SQL 2005 Cluster setup on Windows 2003 R2 between a physical node and a virtual node. Both physical servers are identical 2950's with 2x Xeaon x5460 Quad Core CPUs and 64GB of memory, 16GB allocated to the OS. We are utilizing an iSCSI San for all cluster disks. The problem is this, when utilizing the application under a repeated stress testing that adds CPUs to the cluster nodes, the Physical node scales from 1 pCPU to 8 pCPUs, meaning we see continued performance increases. When testing the node running Vsphere, we have the expected 12% performance hit for being virtual but we still scale from 1 vCPU to 4 vCPUs like the physical but beyond this performance drops off, by the time we get to 8 vCPUs we are seeing performance numbers worse than at 4 vCPUs. Again, both nodes are configured identically in terms of hardware, Guest OS, SQL Configurations etc and there is no traffic other than the testing on the system. There are no other VMs on the virtual server so there should be no competition for resources. We have contacted VMWare for help but they have not really been any suggesting things like setting SQL Processor Affinity which, while being helpful would have the same net effect on each box and should not change our results in the least. We have looked at all of VMWare's SQL Tuning guides with regards to VSphere with no benefit, please help!

• Windows 8 x64 with VMWare Workstation or inside ESXi

  - by Dommer

  I need to run several virtual machines on a core i7-920 box with 12GB or RAM and a 256GB SSD to host the VMs. It also has a Highpoint RocketRaid 2720SGL RAID controller with a 12TB RAID 5 array. I want one of my VMs to run Windows 8 x64, to have access to the RAID array as a native disk (not as networked drives and it needs to run at full speed) and to be able to send files quickly across the network. Initially I thought I'd try to do this using ESXi 5, but I have been unable to find any working RAID drivers for the RR2720SGL and it is not on the HCL for ESXi 5. In light of this, I have installed Windows 8 x64 on the hardware and am thinking of installing VMWare Workstation and running my VMs inside there. I guess my questions are these: How does VMWare Workstation 9 perform compared to ESXi 5? In the real world I mean? Presumably installing Win 8 as the host OS will give me way better performance for that Win 8 machine than Win 8 running under ESXi? I should stick with Windows 8 x64 as the host OS, right? If I install a domain controller VM inside my Win 8 box and join the Win 8 machine to that domain, am I insane (I would guess the Win 8 machine wouldn't see the domain controller until it finished starting everything up, but I don't think that matters)?! is it feasible to give metrics like this and if so, what is the likely value of x? 25%? 50%? 75%? Win 8 under ESXi runs x% as fast as Win 8 installed bare metal.

• Windows Media Center showing Jerky Video on PC

  - by Kris Erickson

  I had to repave my Windows 7 x64 box last week due to a hard drive crash, and for a while everything was running perfectly but now all videos in Windows Media Center are jerky (the sound is fine, they just seem to skip a ton of frames all the time). This is on the local machine, but the same thing happens when I try to stream to my Xbox. The videos all show fine in VLC and Windows Media Player (however exhibit the same problem in Quicktime). I guess I must have installed something recently (in the process of getting all the apps I usually have running on my PC) that caused this but for the life of me I can't figure it out. I have updated to the latest video driver (and then rolled back to the standard Windows 7 driver), I have rolled back all the other drivers that I have installed (I believe). I have uninstalled all the codec packs (I also run TVersity, so I have the TVersity codec pack installed), and I uninstalled TVersity. Nothing seems to help. I have uninstalled windows media center, and reinstalled it from the Programs and Features. I have basically ran out of things to try to fix this, and am almost thinking about reinstalling Windows again. Any suggestions? Edit Specs on the PC (which I figured was unimportant since everything used to work perfectly): Intel Core 2 CPU 6600 @ 2.4 Ghz Nvidia GTS 8800 Built in realtek-audio soundcard 4GB Ram Codecs which are failing: All that I have tried, but at least Xvid, Mpgv (mpeg2 video from a camera), and Wmv (only kinds that I have ready access to).

• What is the best cloud technology to use for MongoDB/GridFS database servers

  - by Nerian

  We are going to launch a service that will require between 1 and 2 GB for file storage per paid user. I am going to use GridFS for storing files. GridFS is a module for MongoDB that allows to store large files in de database. I am pondering the different options for storing the database. But since I am unexperienced at deployment and it is my first time with Mongodb I need your experience. Criteria: I want to spend my time developing my core business, that is, my own application. I am a Ruby on Rails developer. I do not like to mess with server configuration. Hence, I would like a fully managed hosting solution. But I would like to know about any other option, if you think it is worth it. It should be able to scale. Cloud style. Pay as you go. The lower the price, the better. So far I known of these services: https://mongohq.com/pricing https://mongomachine.com/pricing https://mongolab.com/about/pricing/ http://cloudcontrol.com/add-ons/mongodb/ And they seem to be OK for common needs, that is no file storage. But I am going to use GridFS, so the size matters. These services seems to scale, in price, quite poorly. MongoHQ: The larger plan max storage is 20 GB. Seems like a very little storage, for GridFS. MongoMachine: Flat price, 2.5$ per GB. I didn't found the limit. Seems like a good price, comparing the others. MongoLab: 3.984 GB max, which I don't think I will hit, so perfect. 8$ per GB, quite costly. CloudControl: The larger plan is 20 Gb. The custom service starts at 250€ plus some unspecified charge per GB. What is your experience with these services? Any downtimes? Other possibilities? Edit: Added meaning of GridFS

• 100% CPU load on Ubuntu 10.04.3 LTS 64bit

  - by deadtired

  I have 2 days since I am trying to fix this issue, with no success. The server is a mysql database server. Hardware: DELL Poweredge 1950, 2x Intel Xeon Quad Core E5345 @ 2.33GHz, 16 Gb mem, 2x 146Gb SAS (software RAID1) Software: Ubuntu 10.04.3 LTS, MySQL 5.1.41 Issue: while mysql is not used and runs with no database, everything seems alright. As soon as I install a database, it has the reason to bring all 8 cores in 100% with low memory consumption. So, you can imagine the load average goes high (I saw 212 load average for the first time). The server doesn't become unresponsive, but you can see it's slow while browsing the project installed. Additional info: the database used is not more than 24MB and it was moved from a server with less resources and a lot more larger databases. So it's not the database/project. my.cnf is not a reason also, as I used both default one and the one I use on the same distribution on another server.What is interesting is that mysql doesn't close any process and runs to the limit of the max_connections. Logs are quiet. Nothing there. I switched to this Ubuntu version after I suspected some problems in the newly Ubuntu 11.10 server. This one worked alright for an hour after I made a kernel upgrade to 3.0.1 (it was using the memory also) I tested disk speed and seems alright. Some more output on the running server: dstat -cndymlp -N total -D total 3: htop command: Idea? Did anyone meet the same problem? Any fix you can think of?

• Faking a Linux environment without chroot

  - by Pascal

  For a university project I want to test a C++11 program on a 32-core machine. Unfortunately the machine has Ubuntu 12.04 with GCC 4.6 installed (we need GCC 4.7 because of some C++11 threading features). In such an environment I would normally run a chroot with a custom linux (say a debootstrap with Ubuntu 12.10). Since we don't get root access on the machine we can't use chroot. So far I have prepared a run-time environment using debootstrap for our code, I compiled it in the debootstrap environemnt. Then copied it onto the server (using rsync). In order to run our C++ code I set the LD_LIBRARY_PATH to export LD_LIBRARY_PATH=~/debootstrap/usr/lib/:~/debootstrap/lib64/:~/debootstrap/usr/lib/x86_64-linux-gnu/:~/debootstrap/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH and so far our code seems to run. I'm however stuck with our python code. It doesn't seem to be sufficient to set the paths manually. export PYTHONPATH=~/debootstrap/usr/lib/python2.7/dist-packages:~/debootstrap/usr/lib/python2.7:~/debootstrap/usr/lib/python2.7/plat-linux2:~/debootstrap/usr/lib/python2.7/lib-tk:~/debootstrap/usr/lib/python2.7/lib-dynload:~/debootstrap/usr/local/lib/python2.7/dist-packages:~/debootstrap/usr/lib/pymodules/python2.7:~/debootstrap/usr/lib/python2.7/dist-packages/PIL:~/debootstrap/usr/lib/python2.7/dist-packages/gtk-2.0:~/debootstrap/usr/lib/python2.7 Executing our script results in ImportError: No module named _path Is there an easier way to accomplish a "fake"-chroot than just overriding and creating environment variables? Note I need python since we created a custom C++-Python module in order to run our tests. Maybe I should create two questions from this.

• I can't get my PC to start up by a normal way.

  - by ssice

  I couldn't write a more accurate title. I am just unable to start the computer by pressing the Power On button. I checked the Power Supply and it seems to give good voltage values in every pin. And this is not a BIOS malfunction because of bad overclocking or anything that may come to your mind. And I will tell you why. It happens that EPS (or any ATX-based) power supply has the ability to be powered-on by the Motherboard by jumping the 13th pin of the 24-pin-ATX-connector to COM/GND. I did it, after pushing the power on button (without any visual response) and, pwhaa! The machine turned on. I was able to read (and even write, if I wanted) BIOS values and then start any OS installed. Machine starts, so it's not any kind of misconfiguration. It seems some hardware related. I am able to power the machine on only if I already pushed the power on button. Though pushing it without jumping the 13th pin to ground for a second does not power the machine. Of course, jumping the pin without pushing the power on button does not tell the motherboard anything, so the computer would not start up either. It's as if the logic that connects the power button with the 13th pin derivation to GND was unable to be activated. What can be the issue? How can I solve it? My configuration is as follows: CPU: AMD Phenom 9850 X4 Black Edition MB: ASUS Formula II AM2 RAM: 2x2GB Corsair Dominator 5-5-5-15 2T @ 1066MHz DDR2 Tested also with only 1 module GPU: 2x XFX nVIDIA GeForce 9600 GT XxX Alpha Dog Edition @ Core: 540Mhz [SLi] Power Supply: Xilence 700W (ATX 12V 2.3 / EPS 12V 2.92 compatible) PS: I know the machine is like 2 years old. I hardly use it now, but my parents do.

• Important hardware components to avoid bottlenecks/improve speed on a laptop?

  - by joelhaus

  Looking for a powerful general use (including web development) laptop running Windows. Price points seem to be all over the place. Many less powerful machines are priced much higher than machines with better specs. How does one navigate this market? Are there any unpublished/under-publicized specs/bottlenecks you look for? Understanding that hardware improves over time, is there an efficient ratio that can be used (or something similar, like Windows Experience Index?) which will indicate how powerful a system is? Thanks in advance! P.S. Here is an example from a laptop released on September 17, 2010. Can anyone pick apart these specs? Is there missing information you would be looking for?

• Server Recovery from Denial of Service

• Instructions to setup primary and only domain controller

  - by Robert Koritnik

  Where could I get best step by step instructions (with some simple explanations) how to setup domain controller on Windows Server 2008 R2 Server Core? I don't know what do I need? Do I need DNS as well and AD and so on and so forth. I don't know enough about these things, but I need to set them up to prepare development environment. I would also like to know how to configure firewall on DC machine, to make it visible on other machines because I've setup DC somehow but I can't connect to it... This is my HW config: Linksys internet router with DHCP my dev machine is Windows 7 my DC machine is a VM in my dev machine my dev machine has a hw network adapter to linksys and a virtual network adapter to DC DC machine has two network adapters: one to linksys (to be internet connected so it can be updated etc.) and one to host (my dev Win7 machine) Edit My development machine should access domain controller and logon using domain credentials. Development machine would access internet directly via Linksys router. My domain controller machine would only serve authentication (and if I'm able to configure it right) should also have Active Directory Federation Services in a workable condition. I hope this is a bit more clear now. At least a small bit.

• Home Server: storage virtualisation, what to choose?

  - by Huygens

  I'm looking for virtualisation solutions for storage and OS for a home server. A sort of private cloud where I manage the storage space independently of the VM one. This question focus on storage management. (I have another question related to the VM/compute instance management). Here my environement and wishes. Server: HP Proliant MicroServer with 8 GB RAM (AMD Turion dual core with AMD-V technology) with 1 250GB system disk and up to 4 HDD (2 TB) for "data" OS types: only Linux (perhaps a *BSD VM in the future) Linux distributions do not matter, I'm familiar with RHEL, Fedora, Suse, Ubuntu, but any other recommandation will be fine The 4 HDD is going to be a software RAID array, probably RAID 5. storage should be "virtualised/cloudified": easy to extend: if I add a NAS on the network, I can include the NAS space capacity within this storage space as one virtual disk. This can be a NAS, an external HDD or another server. cluster FS or S3 style space or OpenStack block storage? Whatever is easier to manage/maintain and easy to integrate/plug to VM/compute instance. I would prefer free (libre, as in a free speach) and open source tools. But it does not have to be free as in a free beer. Note: the VMs I intend to run on top of this server are one dedicated to backup, one for a "owncloud/dropbox"-like service and perhaps one for media server (hosting video and photos). I'm not sure if traditional VMs or compute instance are the most suitable for this.

• Windows 8 Fails to install with corrupted graphics

  I am trying to install Windows 8 Pro Upgrade via the download method on an older PC (07-08). It is a Dell Dimension E521 but it has been upgraded with a 3.0 Ghz Dual Core AMD Processor, 120 GB SSD, and 4 GB of RAM. The Windows 8 upgrade assistant did not detect any issues or concerns with upgrading other than I don't have DVD software installed. The system install Windows 8 but on the first boot, corrupt graphics are present. Eventually, the monitor will go into sleep mode and then roll back to Windows 7 Pro X64 which runs fine. I wouldn't be upset over not being able to install Windows 8, but I already paid for the software since I thought there would be no issues upgrading. The Graphics card in the system is the Geforce 7300LE and it has the latest NVidia drivers for Windows 7 loaded. I saw this solution which is similar to my problem: Corrupt graphics during Windows 8 installation However, I have downloaded Windows 8 and I am not sure how to go about modifying the install that resides somewhere on the hard drive. Thanks in advance for any assistance.

• Could hybrid SSD + HDD be made with fixed internal partitions?

  - by Aaron

  I was pretty close to getting Seagate's Momentus XT but have been scared off by the many problems reported on forums and feedback sites, especially in Mac Book Pros. So I'm waiting for mk 2 with some extra flash and better reliablilty I'm assuming will come out this year. What would suit me better though is a 32+500 hybrid drive where I have more control over what is on the flash drive and what is on the disk drive. So there are 2 physical partitions within the one 2.5" hard drive enclosure which use different media internally (32GB for core files and 500GB for data and multimedia). The partitions would be locked so they can't be changed. - Or even better, the disk driver just makes them appear as two disks to the OS that share the same bus... Perhaps it's ok if the bios just sees the first drive until the OS is loaded. Is either of it technically possible? Obviously difficult to market outside of the enthusiast market. The SSD memory modules can be pretty small right, so they could even make them a card that plugs into a secondary connection on the enclosure. That would be good for computer builders as well as for upgrading and recoverability. Then future operating systems could recognise these system SSD drives and automatically install the OS + swap files on it. While placing document libraries on the larger data drive. While in the longer term HDD will probably disapear there will always be a trade off between speed, storage size and expense.

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• Installed Bunch of New Fonts on Windows 7 - Now None Show Up and System Lags

  - by Josh Stodola

  So I went to install about 5,000 fonts on my Windows 7 64-bit machine. It was slow to install them, and I had to leave. I came back and my PC was shut down, and I had to go through the Windows recovery BS when I powered it on. Now my computer runs EXTREMELY slow and any program that has a font menu locks up my whole machine (nothing in Microsoft Office works). When I go to "Fonts" in the control panel, it says 0 items. I went through all of the font settings trying to get them to appear. Nothing helps. I tried to bring up the Character Map and that froze up my machine too. How can I fix this? If I do not get this issue resolved soon, I am wiping this drive and going back to XP (and probably never purchasing another version of Windows again). I never had any issues with XP and have had nothing but performance problems when switching to Windows 7. My quad-core intel extreme with 8GB of RAM should never flinch with the kind of work that I do, and something simple like playing a song off an external HD takes up to five seconds on Windows 7. Unbelievable that I had to pay for this crap!

• Advice on Computer Specs for overall development/general use machine

  - by Ender

  At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.
