• How to compare speed of graphics cards in Windows desktop environment?

  - by Al Kepp

  I use Windows 7 and Intel Core i3 CPU with integrated graphics. My problem is that it eats valuable system RAM for display. I can replace it with an old PCIe Radeon X700, so all system RAM will be usable for applications. The question is if an old Radeon X700 is comparable in W7 desktop speed to a new integrated i3 graphics. Are there any test programs which compare the speed of graphic cards in Windows 7 desktop environment (i.e. no Direct3D games, just Windows desktop)? (According to Tomshardware, Radeon X700 is probably even faster than Core i3 in 3D. But there are no native WDDM 1.1 W7 drivers for X700, only WDDM 1.0 Vista drivers are available.)

• Bad I/O scheduler?

  - by user62367

  os: up-to-date Fedora 14. Working as a "normal desktop". It's doing very well, but if i start VirtualBox, and e.g.: install a guest on it, it just "freezez". I mean if there are disk activities on a VirtualBox guest, then the computer becomes unrespondable..even the mouse is laggin for about 50 minutes.. What could be the bottleneck? What could be the problem? If anyone has any tips/howtos to speed it up, please help! It has a normal 2,5" HDD, with 5400 RPM. Does it worth for me if i buy a 2,5" HDD with 7200 RPM? T7200 cpu, 4 GByte RAM, "vm.swappiness = 0". Thank you!

• How to Enable Multirow Bookmarks Toolbar?

  - by IneedHelp

  I have tried using Multirow Bookmarks Toolbar Plus and Roomy Bookmarks Toolbar Firefox add-ons, but the problem is that they are constantly stressing my CPU (even when idling). It probably has something to do with version 11 of the browser. Anyway, is there some clean way to increase the height of the bookmarks toolbar and allow it to display bookmarks on multiple rows? I've read a lot of articles that refer to userChrome.css and I have tried a dozen solutions, but none worked because they were outdated. Please help me with this.

• Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

  - by snitko

  I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either. Any ideas where should I be looking?

• Unlocking AMD Phenom II X2 550 Black Edition cores - what are the risks?

  - by Vilx-

  I've got the above mentioned CPU and a GigaByte GA-MA790XT-UD4P motherboard, which should be capable of unlocking the extra two cores - if I'm lucky and they're not faulty. The Internet is full of instructions on how to do that. What I don't have is spare money to buy new hardware if I brick something. What are the risks when attempting to do this? Is it completely safe, or can I be left with an expensive pile of junk? What should I keep in mind when doing so? Bigger cooler maybe (I'm running with the default box cooler)? Should I lower the frequencies too? I've never done any OC before.

• Xeon X5550 vs Six-core Opteron for database server

  - by gregmac

  I'm specing out a database server, and the price works out to be reasonably close between an Intel X5550 Quad-core and an AMD 2425HE (2.1Ghz) Six-core Opteron. I've been looking for some comparisons between the two, but the only thing useful I've found is an AnandTech Review of the 2435 which compares it to Intel Xeons, but concludes they both have their place. My load is MS SQL Server 2008, with an OLTP database that has about an equal amount of reading/writing (and it's a reasonably heavy load). So my question is, what is going to work better in this situation, assuming the drives are the same: Xeon X5550, with 16GB 1333Mhz RAM (Dell R510) or an Opteron 2425HE (2.1Ghz) or 2439SE (2.8Ghz) with 16GB of 800Mhz RAM? (Dell 2970) Note: the 2439 adds $500, but the overall pricing works out that it's not that much more than the R510. Using the 2425HE, the Dell 2970 server is slightly less than the similarly-equipped R510). If it adds a decent amount of performance, it's worthwhile to go faster. (single CPU, in both cases).

• MySQL on Linux out of memory

  - by Sunrays

  OS: Redhat Enterprise Linux Server Release 5.3 (Tikanga) Architecture: Intel Xeon 64Bit MySQL Server 5.5.20 Enterprise Server advanced edition. Application: Liferay. My database size is 200MB. RAM is 64GB. The memory consumption increases gradually and we run out of memory. Then only rebooting releases all the memory, but then process of memory consumption starts again and reaches 63-64GB in less than a day. Parameters detail: key_buffer_size=16M innodb_buffer_pool_size=3GB inndb_buffer_pool_instances=3 max_connections=1000 innodb_flush_method=O_DIRECT innodb_change_buffering=inserts read_buffer_size=2M read_rnd_buffer_size=256K It's a serious production server issue that I am facing. What could be the reason behind this and how to resolve. This is the report of 2pm today, after Linux was rebooted yesterday @ around 10pm.

• Intel VT-x disappeared after upgrading to Windows 8

  - by StepTNT

  I've upgraded to Windows 8 some weeks ago (MSDNAA!) and today, while I was trying to run a VM, I've noticed that VT-x is disabled. Now, Hyper-V works without problems, as I've tried emulating Win7 and WP8; but VirtualBox says that VT-x is disabled and it can't run my VM. Just to double check, I've run Securable by GRC and the Intel utility and both says that I've got VT-x off. Here comes the problem: VT-x is ON in my BIOS, and it worked flawlessly before upgrading to Windows 8! Any kind of suggestion? EDIT: My CPU supports VT-x: http://ark.intel.com/products/52219

• Is Ubuntu Netbook Remix actually lighter than Ubuntu Desktop?

  - by D Connors

  I'm running ubuntu on my work notebook. While it's not a netbook, it is a relatively weak machine. So, even though I'm not a big fan of the ubuntu netbook interface, I would be willing to use it if it's lighter (on RAM and CPU) than the desktop version. I know there are some very light linux distros available out there, but I'd like to stick with ubuntu both for it's community and for the support I have available here at my workplace. So, is Ubuntu Netbook Remix lighter on system resources than Ubuntu Desktop?

• Options to optimize lotus notes 8.5.X

  - by Jakub

  Has anyone found actually useful optimization methods for the bulky, fat, eclipse giant, nuissance that is Lotus Notes 8.5? I want it to be fast, and not eat up system resources like crazy while I run it ALL day (as it is my company's corporate mail / cal / scheduling solution). I've tried various hacks for the JVM heap size (if I recall correctly). None really bring a performance improvement. I have a dual core cpu, if that helps (I tried going the route of optimizing JAVA for 2 cores in hopes it would work, but seen no speed improvement). Notes is just sooo bloated, anyone have any suggestions to optimize/mod this thing so it is more responsive and less of a resource hog. Note: I don't want to switch to the web version, or the standard stripped down versions, I am aware of those, I just cannot since we don't run those internally for the company.

• Apache Prefork Configuration

  - by user1618606

  I'm newbie on VPS configuration. So, I've installed apache, php and mysql and now I need to know how to configure Prefork to optimize Apache. The system configuration is: CPU Cores 2 x 2 Ghz @ 4 Ghz RAM Memory 2304 MB DDR3 Burst Memory 3 GB DDR3 Disk Space 30 GB SSD Bandwidth 3 TB SwitchPort 1 Gbps Actually, after linux, mysql, apache and php, there are 250 MB memory in use. Well, I don't have idea to calculate. I saw in some websistes, some vars like: KeepAlive On KeepAliveTimeout 1 MaxKeepAliveRequests 100 StartServers 15 MinSpareServers 15 MaxSpareServers 15 MaxClients 20 MaxRequestsPerChild 0 or StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 How I could to do: Prefork or worker? Where and how the vars are placed? In httpd.conf?

• moving to a new dedicated server and need advice on the new setup

  - by Eric Martin

  I currently have a dedicated server that we have outgrown and we are moving to another server. Our current setup was a 8gb W2008R2 server running a W2008R2 IIS virtual machine using VMWare. We are moving to a 2 cpu 24 gb server with W2012 R2 on Hyper-V. On our virtual machine we are running iis 7.5 and sql server. Sql Server seems to want to eat up all the memory so I had to cap it at 2gb, which doesn't seem sufficient. My question is, when I move the virtual machine to the new server, should I create 2 virtual machines, one for sql server and one for IIS? Or should I leave them both on the same virtual machine? Or even, put the Sql Server on the dedicated server and run the IIS in the vm? I'd like some input on how this should be done, I've not got the experience needed to make the right call. Thanks!

• IIS 8 Random 503 service unavailable

  - by Ivo

  We migrated a busy website to Windows Server 2012 with IIS 8. The website randomly gives the error "503 service unavailable" after an user presses F5 the error is gone again. The website is build in ASP.NET MVC 3. The website runs on one application pool, with default settings There are around 500 to 900 concurrent users on the website during the day, and the error happens more often when there are more 650 users. The CPU and the memory use on the server is stable. There is nothing about the 503 errors in the application log, the IIS log and the event log. Does anyone has any clue what the problem can be or how we can trace the the problem?

• How to tell if PAE is hurting me?

  - by James

  I have a couple of servers with 20-30 GB RAM that are running (a variant of) RHEL4. They are currently running the SMP i386 kernel, not x64, not even the hugemem kernel. This means LowMem is confined to < 1G, and thus dentry_cache and ext3_inode_cache to 100M or so each. How can I tell if this is a problem? Here's a typical vmstat report while it's compiling some Java: $ vmstat 10 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 1 0 19493816 394740 922420 0 0 1058 2292 1491 1020 6 3 80 12 2 1 0 19519480 395244 850156 0 0 1179 1412 1329 1195 9 4 75 12 1 1 0 19557368 392616 828344 0 0 1783 1680 1498 1756 14 5 72 9 I don't like the way bi is nonzero when there is so much memory free. I imagine slabtop could point more directly to the problem but I don't really understand how to interpret its output.

• Enabling Surround sound on a Realtek ALC892 via SPDIF, on Windows 7

  - by Alex

  I have a problem with my ALC892, on an ASRock mainboard (ASRock 890FX Deluxe4). I get only stereo sounds if I use SPDIF connection, in general. My amp shows that is getting surround sound only when I use the Test feature of Windows 7. This test feature allows to know which formats are supported by the audio chip. The tests render correctly both Dolby Digital and DTS. You can find this test under Sounds, Playback Devices, Select Digital Audio, then "Properties". I am using Windows 7 x64, with the latest drivers from the official Realtek website. I also tested other driver versions, both from the Realtek website and from the ASRock one, but had no luck. Thanks for the help. Some specs: CPU: AMD Phenom II X4 965 MOBO: ASRock 890FX Deluxe4 (with onboard Realtek ALC892) Audio amp: Onkyo R-380 (works fine with other sources like PS3 and Xbox 360)

• System shuts down immediately after few sconds

  - by Anil

  I have a computer with following specification and was working fine after re-installing the system and refitting sink fan unit. Recently it shuts down automatically after a few seconds. I checked PSU by shorting pin no.s 13 & 14 as well as 14 & 15. It worked well means the PSU fan moves. But I never checked the voltages at different wires. I refitted the heat sink fan by applying thermal paste. but it behaved the same. Again I refitted the Heat Sink Fan, then it worked for 2 minutes and again shut down. Now it shuts down immediately after switching on. Mother board : M26GTM-3VP CPU : AMD athlon PSU : 450 watt Can anyone help?

• Is there a test to see if hardware virtualization (vmx / xvm) are presently enabled within a Linux session?

  - by Dr. Edward Morbius

  I'm writing procedures for configuring VirtualBox support for 64-bit SMP guests, which requires hardware virtualization suppot (VTx/Intel, AMD-V/AMD). I have successfully configured this myself, however I'd like the procedure to be clear. sed -ne '/^flags/s/^.*: //p' /proc/cpuinfo | egrep -q '(vmx|svm)' && echo Has hardware virt || echo No HW virt ... shows if the CPU is capable. I've still got to go enable the feature in BIOS. Any way to test from within Linux to see that this is no or not? Thanks.

• Is there a Windows 7 add-on that will put the PID in the title bar of a window?

  - by Chris

  Occasionally I run many instances of something, like Chrome or Visual Studio. Rarely, but often enough to bug me, one of them gets hosed and starts to consume 100% CPU. I can fire up the task manager to see which process is using 100%, but if it just says chrome.exe or devenv.exe, I don't know which window is the culprit. I'd like to know before terminating the process, so I can activate the app and shut it down cleanly. The best I've found so far is to use Process Explorer's feature where I can right click a process and say "bring to front". But I am curious as to whether there is an app that will put the PID(s) right in the title bar of the window so I can tell which window matches the process. I am using Windows 7 64-bit.

• Configure TV Capture card to not use external audio jack for TV audio output

  - by Adam D.

  I had this working with MythTV on Ubuntu 9.1. Then a power surge killed the motherboard. After replacing the motherboard, ram and cpu, the card does not produce any audio except through the output jack on the back of the card. I do not want to use a cable to go from the back of the card to the audio in on the built in sound card of the new mother board. FYI, the old motherboard did not have an on-board sound card. There was a separate audio card installed. There's some configuration that has to be done to have it work the same way again. I just have no idea where to start. This is regarding wintv hauppauge mythtv linux ubuntu 9.10 audio

• fedora 11 server won't boot from SATA disk, won't boot from CD, BIOS configuration problems

  - by Tom

  Hi all, Yesterday our fc11 file/print server didn't boot, and had stopped on the BIOS page with a configuration problem. (with a distinct lack of foresight) I reset the BIOS settings to default without recording the message and booted the server. The server ran until it was to be booted this morning, and it was failing to mount the root partition from the SATA disk. It also failed to boot from a known good diagnostics CD. After a few more tries, it now fails part way through the Phoenix - AwardBIOS screen where it is listing the SATA/IDE devices, and it is showing garbage for the identity of one of the disks, which should actually be "none" It looks like the motherboard has gone kaput. The motherboard is an EVGA NF790i, are there any diagnostic tools that I can use to determine this? (as I would prefer to not send the motherboard back, only to discover that it is the RAM or the CPU) ps I can't get it to boot from the memTest disk, so I can't run that diagnostic. Thanks!

• Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

  - by jonathanconway

  I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?
