• Bonnie does not provide speed for Sequential Input / Block

  - by Lqp1

  I'm using ProxmoxVE and I would like to run some benchmarks regarding performances of this product. One of these benchmarks is bonnie++ ; it runs very well in a VM (qemu-kvm) but when I run it in a conainer (openVZ), it does not provide me reading speed (only writing). I don't understand why... Does anyone know what's happenning ? VMs ans Containers are Debian 7.4. Here's the output of bonnie in the container: root@ct2:/# bonnie++ -u root Using uid:0, gid:0. Writing a byte at a time...done Writing intelligently...done Rewriting...done Reading a byte at a time...done Reading intelligently...done start 'em...done...done...done...done...done...

Maybe it's related to this issue but I can't find anyone with the same issue with bonnie and openVZ... Thanks for your help. Regards, Thomas.

• i7-980X at 70% speed

  - by Buxley

  Hi we bought a nice computer to use to solve optimization problems. Intel i7-980X@3,33 GHz with 12 GB of Team Group 1600 MHz DDR3 RAM. When we use Gurobi the computer uses all 12 cores at maximum in the beginning of the solve. However after a while (about 8 hrs) it all cores jump between 65 and 85% When I solve the same models on an i7 930 all cores are at a near 100% level even after longer solution times. We first thought that the Hard disk was the bottleneck since Gurobi writes out nodefiles after the memorylimit is used. However since the new computer have 12 GB of RAM we put the memorylimit to 7 GB so the solver only used the RAM and still with the same performance in the processor. Any ideas about the bottleneck? As I said earlier it works at 100% for the first hours or so . Thanks very much for any answers! Our plan was to overclock it but we can't even get it to work at normal speed yet!

• Hard drive write speed - finding a lighter antivirus?

  - by Shingetsu

  I recently have been getting a lot of system lag here (for example, the mouse and the display in general take about 15 seconds to react in the worst cases). After a lot of monitoring the resources, I found that the problem mainly happens when too much Disk I/O is being done. Three culprits have been identified: My browser had the highest write I/O with 35,000,000 I/O Write Bytes. Steam had the highest read I/O (when IDLE!!!) with 106,000,000 I/O Read Bytes. My antivirus (in both cases I will soon mention) was the runner up in both cases with: 30,000,000ish write and 80,000,000ish read. The first AV I had was Avast! which I had liked on my previous system. After noticing it taking so much I/O I switched to Panda (supposing it wouldn't use TOO much during idle phase). However it only used a bit less I/O. Just a lot less memory and cpu and somewhat more network. My browser at the moment is Maxthon 3 (which I like a lot). Before this I was running chrome which had similar data and much higher cpu when running in the background was enabled. I'm not going to be running steam all the time and there aren't many alternatives to it. I like my browser very much, but I AM willing to switch if there's an obvious problem (I'm in programming, however I'm not a very good sysadmin, especially not when it comes to windows). Finally, my system almost stops lagging when I turn off the antivirus (and preferably steam) (some remains but once in every 5-6 hours for a few seconds so it isn't a big problem). My question (has a few parts): Is it possible to configure steam to lower it's I/O usage? (and maybe network while we're at it?) Which antivirus (very preferably free) uses lowest I/O while idle (I leave PC alone during active scans so that isn't a problem). Is there an obvious problem with my current browser and, if so, is there a way to fix it or should I switch and, if so, to what? (P.S. I've been on FFox for some time too). Info on system: Windows 7 (32 bit T_T, I am getting a new one in a few months but I want to keep using system during that time though). Hard Drive (main) is a Raid0. (Also have an external 1TB one which contains steam (and steam alone). As such it doesn't get used by much anything other than steam and isn't a very large problem. However steam still uses some I/O of registry) CPU: Intel(R) Core(TM)2 CPU [email protected] RAM: 6GB (3.25GB usable) (this and CPU have little effect as shown in next section) Additional info: Memory usage during problematic times: 44% CPU usage during problematic times: 35% Page File: main drive: system managed. 1TB drive: none. The current system I'm using is about 6 years old and is mainly a place holder while I await the new one in a few months. Final words: this is my 1st post on Super User (this question wouldn't feel right on Stack Overflow where I usually stay). If it doesn't have it's place here please tell me. If anything is wrong with it, same. Edit Technically I'm looking for a live thread detection program with minimal IO usage. I already have good active scan capability: Kaspersky (the free scanner uses the paid database) and MalwareBytes. Edit 2 Noticed another one, it seems that windows media player has been using stuff even when off! Turning it off and restarting now. If the problem is fixed I'll tell you guys. The reason I didn't notice it before was because I didn't have resource manager in front of me at the MOMENT of the problem. Now I did and it was at the very top of the list!

• windows server 2003 speed issues

  - by farzinSH

  I have a HP server with windows server 2003 and 50 windows XP clients. Since a week and a half the networks speed suddenly drop 2-3 times per day. It gets so slow that none of the clients could work with the HIS program installed on them. We tried so many different things such as replacing the hubs,switches and even some wires. Every time one of these changes solves the problem and the network goes back to its normal state. I checked everything. Even when I disconnected all the clients from the server and connected it to just one computer the problem still remained for 2 hours. I just narrowed down the problem to the couple of likely speculations as follows: viruses? (Updated Kaspersky running on the server shows none) server hardware failure? Physical memory usage on the server? (Because the last time the problem occurred none of the changes above solved the issue so I restarted the server an checked the physical memory usage which was 2 GBs. But I noticed it's increasing over time to over 9 GBs...the server has 16 GBs of RAM.) I surfed the internet and got nothing. Any help would do us a lot....thanks in advance

• what are all the Optimize tricks that you know for asp.net code ?

  - by Aristos

  After some time of many code programming on asp.net, I discover the very big speed different between string and StringBuilder. I know that is very common and known but I just mention it for start. The second think that I have found to speed up the code, is to use the const, and not the static, for declare my configuration constants value (especial the strings). With the const, the compiler not create new object, but just place the value, on the point that you have ask it, but with the static declaration, is create a new memory object and keep its on the memory. My third trick, is when I search for string, I use hash values, and not the string itself. For example, if I need a List<string SomeValues, and place inside strings that I need to search them, I prefer to use List<int SomeHashValue, and I use the hash value to locate the strings. My forth thought that I was wandering, is if is better to place big strings in one line, or separate them in different lines with the + symbol to be more easy to read out. I make some tests and see that the compiler make a good job is some split the string, in many lines, using the + symbol. What other tricks/tips do you know and use on your programming to make it run faster, and maybe use less memory. Well I know, that some times, to make something run faster, you need more memory, more cache. My priority is on speed. Because Speed Counts.

• How to make 7zip faster

  - by user34463

  I normally use winRAR over 7Zip simply because its faster and only a little less efficient with compression. I did a few tests on different filetypes and sizes comparing the 7zip and winRAR default settings on their normal compression and their best compression, and in a lot of cases winRAR was 50% faster and in some it was actually 100% faster. But, I do like FOSS more. So here are my questions: Is there a way to make 7zip speed up? I'd like it to at least be on par with rar's speed Is there a way to make recovery segments in 7zip like you can in rar? I didn't see any, but I guess it could be a command line thing. I tested winrar and 7zip using the latest stable version of each (4.something with 7zip). Is the 9.x beta release noticeably faster at compression? I'm talking about faster at a comparable setting in WinRAR, not just lowering to bare minimum compression. If it matters, I use a quad core intel i7 720 (1.6ghz)/(2.8ghz) with 4gb DDR3 ram, and the 64-bit version of 7zip.

• slow network in centos5 VM with centos5 host running KVM

  - by dan

  I setup KVM following the guide here: http://www.cyberciti.biz/faq/centos-rhel-linux-kvm-virtulization-tutorial/ I setup a bridged network and it worked fine except that the transfer speed is 200KB/s instead of the gigabit speed that I get on the host machine by itself. I tried editing the guest network settings to set "model=virtio" http://wiki.libvirt.org/page/Virtio but this just moves ifconfig-eth0 to ifconfig-eth0.bak in the VM and networking doesn't work at all. I tried moving ifconfig-eth0 back and starting up eth0, which works, but now the transfer speed is ~ 60KB/s I have no idea what else to try. Any suggestions would be greatly appreciated.

• Increase data transfer speed through bonding/lacp?

  - by Matteo

  I want to maximize the throughput of a data transfer between two servers. The copy will be made at the application layer using Robocopy. To clear things up, please check my Visio schema of the network: FS1---------(SW1)===========(SW2)--------- FS2 SW1 to SW2 is connected through 10 gigabit Fiber Channel ethernet FS1 to SW1 is connected through 1 gigabit ethernet FS2 to SW2 is connected through 1 gigabit ethernet I first idea I've come up with is to use LACP, so I could use two Gigabit Ethernet between each server and the switch. A collegue told me that LACP is for availability and not performance, so he reckon this solution will not work. Is he right? Do I have other options? Thank you very much

• Software way to cool down an old MacBook Pro

  - by notMacBookProSuperUser

  Hi all, First a little background: I've got lots of computers, including Linux PCs and two MacBook Pro (and a MacMini). My concern is with my 'old' MacBookPro (Core Duo). It really does overheat. Warranty is long void. Years ago (I'd say 2.5 years ago or so) one day it overheated so bad that the battery inflated due to the heat. I got a new battery for free but it's still getting incredibly hot (much other than any other computer I've got: my newer Core 2 Duo MacBook Pro doesn't get nearly as hot as the old one. It s really a pain because I use my old MBP when I m in front of TV, having it on my lap, and it can really become unbearable. I don't want to open that old MBP. On Linux I can force a new CPU 'governor' that decides how the CPU is allowed to operate: it can be 'on demand', 'always max speed', 'always speed x', etc. Does the same exist under MacOS X? Is there a way, say if a 1.86 Ghz Core Duo can run at 1.6 Ghz, to ask MacOS X: "never run this CPU above 1.6 Ghz" ?

• Memory modules not running at rated speeds.

  - by Wesley

  Hi all, I'm having some odd memory issues with my build. Here are my specs right now: QDI Superb 4 motherboard Intel Pentium 4 Northwood 2.4GHz (512KB L2, 533MHz FSB) 3x 256MB PC2100 DDR266 RAM 16MB NVIDIA TNT2 Pro AGP Seagate 80GB IDE HDD Generic USB 2.0 PCI Generic Modem PCI Bestec 250W PSU To be even more specific, here are the current brands and models of each module: Kingston KVR266X64C25/256 Samsung PC2100U-25331-Z SMART SM5643285D4N0CHM0H Supposedly, they are all PC2100 266MHz modules with a latency of 2.5. Looking in Speccy, the Kingston module is somehow running at a speed of PC2300 ~284MHz. I've never overclocked RAM at all as I don't know how to. However, when I first started the computer, I had the SMART module in place first and then reset the BIOS settings, including the integrated overclocking options. However, this still doesn't explain why the Kingston module runs at a higher speed than the SMART and Samsung module. Why is it like this? On a side note, where could I find the motherboard manual for the QDI Superb 4? Thanks in advance.

• Can I make ruby send network traffic over a specific iface?

  - by rjorgenson

  I am writing a script that grabs the external IP address along with some other information about each iface. I can't figure out how to make ruby send traffic over a specific iface(eth0 and wlan0 for example). I am currently using the open-uri library to open http://whatismyip.org and read it into a variable. def get_external_ip begin open("http://whatismyip.org") { |f| return f.read } rescue return "none" end end Is there any way to specify this at runtime of the script or from within the script itself(ideally)?

• Network Drive Via Ethernet Port for Speed?

  - by Yar

  I have a Macbook with Firewire 400 and USB 2.0, so the only way I can get fast external storage is through the Ethernet port. A really fast firewire 800 drive on ANOTHER computer is actually much faster than the built-in drive (according to XBench). So I thought I would try to go one better and buy an ethernet-ready drive. I bought a Seagate GoFlex™ Home Network Storage System, and it seems like the only way to get it to work is to plug it into a router. Can this drive be used without a router (i.e., direct to computer)? Are there any drives that can be plugged directly into the ethernet port for fast access? I don't want the drive on my router: I want it on my computer. Ideally I'd need 7200rpm or faster, too... Update: Just chatted with Seagate and they said that this particular drive will not work that way. Will any others?

• Limited bandwidth and transfer rates per user.

  - by Cx03

  I searched for a while but couldn't find anything concrete, hopefully someone can help me. I'm going to be running a Debian server on a gigabit port, and want to give each user his/her fair share of internet access. The first objective is easy - transfer rates (speed) per user. From what I've looked at, IPTables/Shorewall could do the job easy. Is this easy to setup, or could one of you point me at a config? I was hoping to limit users at 300mbit or 650mbit each. The second objective gets complicated. Due to the usage of the boxes, most of the traffic will be internal network traffic that does NOT get counted to the quota. However, I still need to limit the external traffic, and if they go over, cut off access (or throttle traffic to a very low speed (10mbit?)). Let's say the user has a 3TB external traffic limit. The IF part is: If the hostname they are exchanging the traffic with DOES NOT MATCH .ovh. or .kimsufi. (company owns multiple TLDs), count to the quota. Once said quota exceeds 3TB, choke them. Where could I find a system to count that for me? It would also need to reset or be able to be manually reset on a monthly basis. Thanks ahead of time!

• New router, slower internet connection?

  - by qwerty

  So, we just bought a new router a few hours ago, and it does work. However, for some reason the speed is just ridiculously slow (compared to before, at least)! If i run a test on speedtest.net i get the following results: http://i.imgur.com/68JyH.png which are pretty good. But for some reason it's like the connection just "hangs" for a second when i navigate to a site through the browser (have tried different browsers). It's not on all sites, it kind of happens randomly. I think the browser cache might be speeding some sites up, because if i visit a site that i HAVEN'T visited before (since i cleared my cache), it takes like two seconds (if not more) to open the site. If i have visited it, it opens directly (it barely loads). Not sure what to do, really. Any suggestions on what might speed it up? Any settings i can play with in the router settings? The router is of the brand Belkin. I'm not sure about the model though, it says "Belkin, Play Max Wireless Router" on the box? Thanks in advance! EDIT: Alright, it takes a lot more than two seconds. At least 3-4 depending on the site. Any suggestions?

• Ubuntu 9.10 Dowload Speed Very Slow

  - by Don

  I'm running Ubuntu 9.10 desktop and I'm new to the Linux world, so bear with me. I'm on a corporate network of 3 T1s shared across 50-60 users. I typically get about 300 KB/sec for downloads, but for whatever reason, the Linux box will start out in that range, then drop to less than 1KB/Sec sometimes. Doesn't seen to matter where I'm downloading from. Right now I'm trying to get Eclipse for PHP and it's running at 3-6KB/sec. Getting the updates for the system will also drop to very slow rates. Our IT person has set up the machine to get the same 10.0.0.x address when it starts, and moved this IP to bypass our Proxy/Firewall going out, so that shouldn't be the issue. Can anyone recommend something I can try to better diagnose the problem. Again, I'm new to the Linux world and the hardware/OS setup side in general (coming form more of a coding background). Thanks for any advice.

• Windows 7 File Transfer Speed over Gigabit is slow

  - by Adam Haile

  I've got windows 7 pro running on my file server and my main desktop. Each has a gigabit network connection and I'm connected to a gigabit switch. However, when trying to copy some large files, it's running pretty slow at a measly 12-15 MB/s The data is coming from a 7200RPM SATA drive (which I think should be good for almost 150MB/s) and going to a Drobo on the server connected via FireWire 800, so I can't think of any bottlenecks I might have in the hardware. But TeraCopy still says it's only going at 12-15 MB/s What else could be wrong here?

• SQL SERVER – Sends backups to a Network Folder, FTP Server, Dropbox, Google Drive or Amazon S3

  - by pinaldave

  Let me tell you about one of the most useful SQL tools that every DBA should use – it is SQLBackupAndFTP. I have been using this tool since 2009 – and it is the first program I install on a SQL server. Download a free version, 1 minute configuration and your daily backups are safe in the cloud. In summary, SQLBackupAndFTP Creates SQL Server database and file backups on schedule Compresses and encrypts the backups Sends backups to a network folder, FTP Server, Dropbox, Google Drive or Amazon S3 Sends email notifications of job’s success or failure SQLBackupAndFTP comes in Free and Paid versions (starting from $29) – see version comparison. Free version is fully functional for unlimited ad hoc backups or for scheduled backups of up to two databases – it will be sufficient for many small customers. What has impressed me from the beginning – is that I understood how it works and was able to configure the job from a single form (see Image 1 – Main form above) Connect to you SQL server and select databases to be backed up Click “Add backup destination” to configure where backups should go to (network, FTP Server, Dropbox, Google Drive or Amazon S3) Enter your email to receive email confirmations Set the time to start daily full backups (or go to Settings if you need Differential or  Transaction Log backups on a flexible schedule) Press “Run Now” button to test You can get to this form if you click “Settings” buttons in the “Schedule section”. Select what types of backups and how often you want to run them and you will see the scheduled backups in the “Estimated backup plan” list A detailed tutorial is available on the developer’s website. Along with SQLBackupAndFTP setup gives you the option to install “One-Click SQL Restore” (you can install it stand-alone too) – a basic tool for restoring just Full backups. However basic, you can drag-and-drop on it the zip file created by SQLBackupAndFTP, it unzips the BAK file if necessary, connects to the SQL server on the start, selects the right database, it is smart enough to restart the server to drop open connections if necessary – very handy for developers who need to restore databases often. You may ask why is this tool is better than maintenance tasks available in SQL Server? While maintenance tasks are easy to set up, SQLBackupAndFTP is still way easier and integrates solution for compression, encryption, FTP, cloud storage and email which make it superior to maintenance tasks in every aspect. On a flip side SQLBackupAndFTP is not the fanciest tool to manage backups or check their health. It only works reliably on local SQL Server instances. In other words it has to be installed on the SQL server itself. For remote servers it uses scripting which is less reliable. This limitations is actually inherent in SQL server itself as BACKUP DATABASE command  creates backup not on the client, but on the server itself. This tool is compatible with almost all the known SQL Server versions. It works with SQL Server 2008 (all versions) and many of the previous versions. It is especially useful for SQL Server Express 2005 and SQL Server Express 2008, as they lack built in tools for backup. I strongly recommend this tool to all the DBAs. They must absolutely try it as it is free and does exactly what it promises. You can download your free copy of the tool from here. Please share your experience about using this tool. I am eager to receive your feedback regarding this article.

• When "W" is held, the character moves forward, but when "W" and "A" is held, movement completely stops

  I am making a 2D game, and when I hold the key "w", the player goes forward, but when I hold both "w" and "a", the movement stops completely, when I want it to go forward, while shifting to the left. Here is my script: var speed = 4; function Update() { // Make the character walk forward if "w" is being held if(Input.GetKey("w")) { rigidbody.velocity = transform.forward * speed; } // Stop the movement if "w" is not being held if(Input.GetKeyUp("w")) { rigidbody.velocity = transform.forward * 0; } // Make the character walk forward if "s" is being held if(Input.GetKey("s")) { rigidbody.velocity = transform.forward * -speed; } // Stop the movement if "s" is not being held if(Input.GetKeyUp("s")) { rigidbody.velocity = transform.forward * 0; } // Make the character walk left if "a" is being held if(Input.GetKey("a")) { rigidbody.velocity = transform.right * -speed; } // Stop the movement if "a" is not being held if(Input.GetKeyUp("a")) { rigidbody.velocity = transform.right * 0; } //Make the character walk right if "d" is being held if(Input.GetKey("d")) { rigidbody.velocity = transform.right * speed; } // Stop the movement if "d" is not being held if(Input.GetKeyUp("d")) { rigidbody.velocity = transform.right * 0; } } PLEASE MAKE THE CODE BETTER! I AM NEW! EDIT: Here is a video to show my problem. http://www.screenr.com/3oxH Here is the newest code: var speed = 4f; function Update() { if(Input.GetKey("w")) { rigidbody.velocity = transform.forward * speed; } else if(Input.GetKey("s")) { rigidbody.velocity = transform.forward * -speed; } else if(Input.GetKey("a")) { rigidbody.velocity = transform.right * -speed; } else if(Input.GetKey("d")) { rigidbody.velocity = transform.right * speed; } if(Input.GetKeyUp("w")) { rigidbody.velocity = transform.forward * 0; } if(Input.GetKeyUp("s")) { rigidbody.velocity = transform.forward * 0; } if(Input.GetKeyUp("a")) { rigidbody.velocity = transform.right * 0; } if(Input.GetKey("d")) { rigidbody.velocity = transform.right * speed; } if(Input.GetKeyUp("d")) { rigidbody.velocity = transform.right * 0; } }

• Slow boot on Ubuntu 12.04, probable cause the network connection

  - by Ravi S Ghosh

  I have been having rather slow boot on Ubuntu 12.04. Lately, I tried to figure out the reason and it seems to be the network connection which does not get connected and requires multiple attempts. Here is part of dmesg [ 2.174349] EXT4-fs (sda2): INFO: recovery required on readonly filesystem [ 2.174352] EXT4-fs (sda2): write access will be enabled during recovery [ 2.308172] firewire_core: created device fw0: GUID 384fc00005198d58, S400 [ 2.333457] usb 7-1.2: new low-speed USB device number 3 using uhci_hcd [ 2.465896] EXT4-fs (sda2): recovery complete [ 2.466406] EXT4-fs (sda2): mounted filesystem with ordered data mode.
