• my.ini optimization on Windows 2008 R2 VPS

  - by MKphpDev

  I have a vmware VPS running Windows Server 2008 R2 Enterprise that has performance issues with MySQL. Every few minutes, MySQL stall for few seconds then responed to queries. I'm sure that my.ini need to be optimized, but unfortunately, I don't have any idea of my.ini configuration. What's running on the server: 2 small wordpress blogs, 1 vbulletin forums (approx. 1.2 GB database, and increasing), small database for some sort of plug-ins (no more than 4000 records) Server Info: Processor: Intel Xeon X5550 @ 2.67GHz, RAM: 6 GB (memory useage never exceeded 2 GB), MySQL 5.5, PHP 5.3.10, IIS 7 current my.ini: [mysqld] default-storage-engine=INNODB sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE _USER,NO_ENGINE_SUBSTITUTION" max_connections=250 myisam_max_sort_file_size=20G innodb_additional_mem_pool_size=256M innodb_flush_log_at_trx_commit=1 innodb_log_buffer_size=8M innodb_buffer_pool_size=512MB innodb_log_file_size=128M innodb_thread_concurrency=10 key_buffer_size = 512M myisam_sort_buffer_size = 8M join_buffer_size = 256K read_buffer_size = 256K sort_buffer_size = 256K table_cache = 4000 thread_cache_size = 200 wait_timeout = 30 connect_timeout = 10 tmp_table_size = 32M max_allowed_packet = 1M max_connect_errors = 10000 query_cache_size = 16M query_cache_limit = 2M query_cache_type = 1 query_cache_min_res_unit = 1024 query_prealloc_size = 16384 query_alloc_block_size = 16384 skip-external-locking read_rnd_buffer_size=1M max_heap_table_size=16M thread_concurrency=8 [mysqld_safe] open_files_limit = 8192 [mysqldump] quick max_allowed_packet = 16M [myisamchk] key_buffer_size = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M any help with that, please?

• Which OS should I boot into for virtualization?

  - by acidzombie24

  This might be a silly question. I use windows 7 99% of the time. I run linux 10% of the time and XP 5% of the time. I am thinking about getting a Intel® Core™ i7-2600 Processor which has hardware support for virtualization. I dont think i want more than one partition. May have a swap partition. Which OS should I make my primary (and only) partition? I suspect windows7 if i am always using it as going through a linux layer would slow it down. Does it matter much which OS i use if i have hardware support for virtualization? At the moment I am using VMWare player. I suspect software doesnt effect performance?

• What is the best CPU I could get for my old setup?

  - by cmbrnt

  On my current not-so-good desktop computer, I'm currently running an Intel Core 2 Duo E6550-CPU, and I'm thinking of buying a newer one now that these must be cheap on E-bay and the like. Being a software guy, I'd be grateful for any help in identifying what CPUs that would fit my motherboard so I don't buy a processor which won't work with my computer. It might not be worth it however, since the SATA2-drive is currently what's bottlenecking my system, but I'm still curious about what could be done except for buying an SSD-drive. I'm providing screenshots of CPU-Z running, to help with the identification. My CPU- and motherboard info: http://i.imgur.com/YdO8x.png

• Timing startup processes?

  - by acidzombie24

  My Windows 7 use to boot up fast and now its getting rather slow. I suspect one program is eating up all the time yet i cant tell what it is since task manager shows <40% of the cpu being used. What can i use to track how long each process takes when my computer boots/starts up? Note: Except for launchy which i used before my comp became slow, all my startup and services are all signed and known (broadcom, VMWare, Google Inc, Intel, etc) Note2: I am mostly considering the time it takes after i login but i suspect the time before that is slightly slower (i dont think very much though)

• Is ceph usable with only 100Mbps bandwidth between nodes?

  - by vaab

  I haven't great hardware, but my requirements are low, I would like to start using ceph so as to abstract filesystem location and allow potential easy scaling to bigger hardware in an hypothetical future. My actual hardware meets ceph hardware requirements except the ethernet bandwidth part between the hosts. Mine is 100 Mbit/s which is much lower than the 1Gbps expected in ceph, even from the minimal requirement. Will I be able to use ceph in a very small smili-prod environnement (with limited number of clients) ? FYI: My hardware is 2 or maybe 3 hosts having each 4 core Intel, 24Go RAM, 2x2To disks but 100Mpbs between them.

• Display issues on new OpenSUSE install

  - by user1319182

  I installed OpenSUSE 13.1 on my newly built PC, but the display is just horrible : the edges of the screen are missing. For example, I can't see all the top part, I can barely read the date and I see "ctivities" instead of "Activities". However, when I take a screenshot everything seems to be fine (the cursor doesn't appear though) the characters are sometimes too big and sometimes too small the cursor is huge and many other strange things. I took a few pictures I'm using an Intel integrated GPU (HD4400) and made all the possible updates with YaST. Any idea how I can fix this? Thanks

• Windows 7 very slow after restart, but fine after complete shutdown?

  - by lkm

  I have a Dell pc running Windows 7 with the Intel i3 processor. Whenever I restart the computer, the os crawls. For example, I move the mouse and then I see it move on the screen 10 seconds later... Everything runs slowly. This happens only on a restart (it's fine when I turn it on after it has been shut down). Any ideas what is causing this (I haven't installed any new software since buying it). Does it sound like a hardware or software issue?

• Slow remote desktop connection to VPS

  - by Jonathan

  When I use Windows 7's remote desktop connection to our company's VPS (Win Server 2008 32bit) I receive a very slow connection - most of the times it actually grinds down to a complete halt. This is in contrast to my team mates which have no problem remoting to the VPS. I'm using a brand new Dell Studio 1558 laptop with Intel Core i7 and 4GB RAM with a clean installation of Windows 7 64bit Ultimate. Any suggestions for how to diagnose \ solve \ workaround the problem would be appreciated. UPDATES: I checked, and it seems the problem exists with all the computers connected to my home LAN. Once I take my laptop to the nearest coffee shop it works fine. What could be the problem with the LAN?

• Origin of display connector numbers in XServer (e.g. HDMI1, HDMI2, DP1)

  - by Andreas N

  a custom mainboard has a DVI and a DisplayPort connector on the board. Currently, everything that is connected at DVI will be named "HDMI2" in XServer. I can see that by calling the "xrandr" tool (in Ubuntu Trusty Tahr). A display connected to the DP connector will be named "DP1" or "HDMI1", if I use a DP-to-DVI adapter. We are now testing a slightly upgraded board version, which has a newer CPU (Intel J1800, Baytrail) among other things and the position of the DVI and DP connectors are switched. Also, everything at the DVI port is called "HDMI1" and something connected to the DP port gets "DP2" or "HDMI2". Q: What causes these numbers to be produced in this manner and where (probably in the kernel) is it happening? I suspect the cause to be hardware related. Specifically, at which CPU pins the connector pins are routed and attached to. Q: Would it be possible to influence this numbering scheme in order to retain the previous numbering behaviour?

• Is the quadro 4000 still worth it's price? [closed]

  - by aknewhope

  I am going to be purchasing a quadro graphics card for learning 3d CAD at work. It's not critical I have it right now otherwise I would just buy the current 4000 (PC). I am buying this with my own money and am concerned Nvidia will release a new Quadro 4000 sometime in the near months. Is the current 4000 still worth it's price tag at $700.00? If i were to purchase it, how long would it be useful? I am going to be running E-PLAN, SOLIDWORKS, DRAFTSIGHT, MASTERCAM. My computer is a second generation i7-2600k with z68 chipset (intel DZ68BC mobo).

• Issues with new graphics card and drivers

  - by Ortund

  With my onboard graphics card (Intel HD 4000) I was able to use 1680x1050 screen resolution. Using the same screen and an Asus ENGTS250 graphics card with 296.10 drivers installed, I'm not able to use that resolution anymore. Also, I've been having other trouble with driver installations. Using 340.52 or 337.88, I can't boot into Windows 7. I see the Windows Welcome screen and then the screen goes black, loses signal and the computer locks up. I think the drivers issues and the resolution problems go hand-in-hand. I have a feeling I could use a newer driver than 296.10 which would give me access to use the 1680x1050 resolution I want to use, but I'm terrified that if I update or install another driver, that the computer will lock up again. Can anyone recommend a [better] driver for me to use?

• Missing Driver - Video Controller (VGA Compatible)

  - by arahant

  I have a HP 2000-2106TU Notebook PC running Windows XP. I want to get the brightness keys to work. They are placed over the F2 and F3 buttons and are meant to be used in conjunction with the Fn key. But these combinations do not work, though other Fn keys such as the volume control keys do. I see a missing driver for a device called Video Controller (VGA Compatible) in the Windows Device Manager. The hardware id is PCI VEN 8086 DEV 0106 SUBSYS_1858103C which a Google search suggests is in an Intel HD Graphics family, but I don't know where to locate the driver. HP's driver scan does not help, as it does not show any missing driver related to video/graphics. What can I do next?

• Booting drops to EFI shell but boots normally if exit'ed

  - by wittybear

  (first post here... I'm normally on stackoverflow) I'm booting an Intel ME 5788 board which uses EFI (a replacement for BIOS). On boot it drops out to the EFI Shell and the 'map' shows the drive as a blockdevice but there is no filesystem device mapped. If I just type 'exit' it boots normally to windows 7 and the configuration (using bcdedit.exe) looks fine. I'm confused - surely if its not been able to map the blockdevice as a filesystem device it should not boot? I would like to be able to get the boot to proceed without my interaction - does anyone know how to do it? (Also there is no Boot Manager options available in the shell, i.e. autoboot, bcfg etc)

• What do BCU.exe and BCUService actually do?

  - by ChrisF

  I've got a Gigabyte G32M-ES2L motherboard with an Intel Core 2 Duo E7500 2.93GHz CPU running Windows XP SP3 (fully up to date). Today when I booted the machine my firewall (Sygate Personal Firewall) warned me that BCUService.exe wanted to make a call out to the internet. Wondering what they were I did a Google search and while I found out that these programs weren't malware, I didn't find out what they actually do. The information seemed to boil down to: Part of Browser Configuration Utility Auto-recovery Service from DeviceVM, Inc. This program is not important for your system process, but should not be terminated unless suspected to be causing problems. Source So before I remove them from my system does anyone know what they actually do and its it worth them taking over 4Mb of memory?

• phpmyadmin error #2002 cannot connect to mysql server

  - by Joe

  I am getting the error in the title when trying to connect to my MySQL server. I have reinstalled MySQL and PHP several times and tried a slew of command line work based on information I searched out. web.mysql is running and I know that my mysql.sock exists and is located in ~/private/tmp/ and also in ~/tmp/. I also have plenty of hard drive space. I have installed and setup phpMyAdmin correctly only adding a password to 'Password for config auth'. I have also connected to the server via Sequel Pro. Why can't I connect to the server via phpMyAdmin? I'm on a 64-bit Intel Mac running Snow Leopard

• EC2 Windows 2008 VM import Not Working

  - by remack

  I am trying to upload a Windows 2008 SP2 server image to Amazon EC2, but once the process is complete, I can't connect to it. I had ops export a VMDK from our datacenter. The image appeared to have a fixed IP, so I loaded it in VMWare player and enabled DHCP. I uploaded it following amazon's instructions: http://aws.amazon.com/ec2/vmimport/ I start the new instance and try to RDP to the public DNS; connection fails. My two thoughts are: Loading it in VMWare player messed it up somehow, since the instructions say use an ESX image. The image they made me had the wrong network adapter type. The image has an Intel(R) PRO/1000 MT adapter using the E1G60I32.sys driver.

• How to make one CPU to be used simulataneously be three different users

  - by beginning_steps

  As a bootstrapping start-up we are thinking of saving on the IT hardware cost by making more use of the hardware that we have. As a solopreneur I have a laptop config : intel core2duo processor, 3Gb RAM and 250 GB RAM. Now we are planning to increase our team to 3 members. Will like your suggestions on the nest cost-effective step that I can take so that I can use the computing power of the existing laptop to act as a kind of server and then buy to more monitors where the new recruits can do the daily work on and they need to have different login id and access and they dont need access to all the files/applications as are available in my laptop. We use internet intensively to do our day to day activity. Please share you experience, whether you think this is a good ploy or there is any other more effective way of achieving the same result.

• What components should I upgrade to squeeze more life of my pc? [on hold]

  - by Jared

  Hi my current specs are CPU: Intel Core i5 750 2.66 GHz, Socket 1156 Motherboard: Asus P7P55 LX Motherboard, Socket 1156, 4xDIMM DDR3, 2xPCIe-16, 3xPCI, 2xPCIe-1, 14xUSB2, Audio, 1xATA, 6xSATA, RAID, ATX HDD: Seagate Barracuda 7200.11 ST31500341AS Hard Disk Drive, 1500GB, 7200rpm, 32MB Cache, SATA-2 RAM: G.Skill Ripjaw F3-12800CL8D-4GBRM, 2x2GB, DDR3-1600, PC3-12800, CL8, DIMM Video: MSI Radeon 5850 R5850-PM2D1G Video Card, 1024MB, DDR5, PCIe-16, DVI, CrossFire, HDMI PSU: Vantec ION2, 620W ATX PSU, SLI Ready, Black Firstly I know it badly needs an SSD, for which I'm thinking of the Samsung 250gb 840 EVO series. The ram could do with another 4GB, for which I am thinking of replacing the 2x2GB for 2x4GB of the same type. My video card is struggling with the latest releases, so vitally should I ditch the video card and go for something newer (ATI 7850, GTX 660?) or try and get another 5850 for crossfire support? Bearing in mind 5850's are sort of hard to come buy now as they are not stocked in shops usually, which means they have to be bought second hand.

• One motherboard crashed. Changed and wants to crash again

  - by CoachNono

  My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years... Here are the specs: ASUS P5N-D Motherboard LGA 775 NVIDIA 750i SLI Intel Q6600 2X EN9600GT 512mb 650w Corsair

• Ubuntu server header timeout

  - by Tabatha M

  I'm running Ubuntu Linux 12.04.1 Kernel and CPU Linux 3.2.0-30-generic on x86_64. Intel(R) Xeon(R) CPU E31230 @ 3.20GHz, 8 cores I recently came across this problem. I'm using apache2/php latest and when I run $url_headers = @get_headers($url); Inside PHP it would normally take milliseconds to within a second to get the headers. Now recently it can take up to 15 seconds or even timeout. It has worked great for over a year and recently started doing this. I'm not sure how to go about fixing it, any help would be greatly appreciated. Thank you

• what may cause unexpected log outs?

  - by lalebarde

  Sometimes, my Linux PC unexpectedly closes my session (log out) while I am working, and puts me back the login window. If I have terminal 1 logged with root and 2 logged with another user (without X), these ones are not logged out. For example, for the last three hours, it has happened five times. Other times, it leads to a reboot. So I have investigated: the UPS, but the behaviour is unchanged without it). the temperatures, but everything is fine (cpu, disks, video card). I have started to investigate also: the memory (partially tested - I have to run a full testyt next night). EDIT: totally tested and passed. My configuration is: Linux 2.6.37-tuxonice x86_64 Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz. Any idea please?
