  • How to Check the Performance of VPS?

    - by Ngu Soon Hui
    I have subscribed to a VPS offered by a hosting provider. The guaranteed performance 1GB RAM, 1M bandwidth. But I found that from time to time the websites can be very slow, so slow that it could take more than 30 seconds to load a simple Joomla website. However the website resumed the usual speed after a few minutes. This created a problem for me when I want to report the performance problem to the hosting provider. They would say to me "see, no problem". Of course there is no problem because the problem is only there for a few minutes , and everything is normal. This ocassionally-slow problem will bug me a few days later and the cycle repeats. Any idea how to solve this problem?

  • How do I install Visual Studio 2010 Express somewhere besides C:?

    - by TwentyMiles
    I have a SSD as my primary (C:) drive, mainly used for quickly loading games. It's pretty small (~30 GB) so I want to keep things that don't really need a speed boost off of it. I attempted installing the Visual Studio 2010 Express beta last night, and It claimed to require 2.1 GB of space so I changed the install directory to a secondary, non-SSD drive. After this, the installer said that it would use 1.8 GB on C: and ~200 MB on the secondary drive. While this token gesture of moving 1/10 of the app to the place I told it to is cute, I really want to install everything I can to the secondary drive. Is there any way to install all of Visual Studio 2010 Express to a drive besides C:?

  • Get lots of javascript problems when using Opera 11.00 to surf

    - by s hanley
    Sites like ebay and even superuser stop working properly when I use opera 11.00. Menus stop working everywhere from ebay to godaddy. Hovering on a menu item doesn't expand it, no sub menu slides out. This makes a large number of very popular websites unusable. Am I right in assuming this is a javascript issue? I use opera for the turbo feature (I have tested opera with and without turbo so it's not turbo's fault) because I'm on mobile broadband until I get my phone line sorted out. Turbo helps me save money, as well as allowing me to surf at a sane speed. Is there a firefox or chrome equivalent to opera turbo that doesn't cost money? I'm using Opera 11.00, build 1156.

  • Memory works fine separately, but not together

    - by patersonjs
    I've been given four 1GB Corsair DDR2 memory modules, and am trying to fit them into my computer but am getting BSOD on Windows XP and errors in Memtest86+. I've tried to identify if one particular module is faulty by trying them in pairs. They work fine in pairs, but when all four are inserted, Memtest86+ reports errors. The motherboard is an Asus P5N-E with dual channel support and the modules are all the same model (same speed, capacity and timings) but one pair is a different hardware revision. One is v2.1 and the other is v2.2... the voltages are the same too. Would this minor difference be a possible cause of the problem? I've got the BIOS memory timing settings all at AUTO - should I manually set the timings?

  • (Windows 7) Dial Up Connection Locks up the Networking Service

    - by Nick
    I connect to the internet by using my cell phone as a dial up modem. (shh, don't tell my service provider) The connection is usually seamless and the speed is good (150kbps) but occasionally, the connection will get terminated by either the phone or the network, I'm not sure which and then Windows7 stubbornly doesn't acknowledge that the connection is dead so I can re-dial. I have tried to manually kill the connection, but then anything related to the network service refuses to open and the connection is still there. No "Network and Sharing Center", "Network Devices" and often the tray menu will refuse to pop open. The only way I have found to clear the problem is a full restart which. Logging off doesn't work and I haven't been able to find the service that is frozen. If anyone knows how to fix this or prevent this from happening or even how to go about troubleshooting I would be very grateful. ps. This problem is non-existant when tethering in linux on the same machine. (Ubunutu 9 and JoliOS)

  • How Lenovo x200(x61) tablet is so great for programming? whats up with so low GHz processors for deb

    - by Piddubetskyy
    for best laptop for programming after reading here looks like its Mac vs Lenovo (tablet, because tablet is only why I would choose it over Mac). I do crave that tablet but low speed processor scares me. Intel Core i5 or i7 in Sony Vaio sounds more attractive (2,26 - 3GHz for lower price). Yes, Lenovo can be fast, like x201, but with good specifications its over $2,000 its a little too much. For a lot of development I just don't want to wait every time while program compiles and builds during debugging. I want it fairly fast and smooth. Can anyone advice their experience with Lenovo's tablets?

  • What to use to wait on a indeterminate number of tasks?

    - by Scott Chamberlain
    I am still fairly new to parallel computing so I am not too sure which tool to use for the job. I have a System.Threading.Tasks.Task that needs to wait for n number number of tasks to finish before starting. The tricky part is some of its dependencies may start after this task starts (You are guaranteed to never hit 0 dependent tasks until they are all done). Here is kind of what is happening Parent thread creates somewhere between 1 and (NUMBER_OF_CPU_CORES - 1) tasks. Parent thread creates task to be run when all of the worker tasks are finished. Parent thread creates a monitoring thread Monitoring thread may kill a worker task or spawn a new task depending on load. I can figure out everything up to step 4. How do I get the task from step 2 to wait to run until any new worker threads created in step 4 finish?

  • Do HTTP reverse proxies typically enable HTTP Keep-Alive on the client side of the proxied connection and not on the server side?

    - by LostInComputer
    HAProxy has the ability to enable HTTP keep-alive on the client side (client <- HAProxy) but disable it on the server side (HAProxy <- server). Some of our clients connect to our web service via satellite so the latency is ~600ms and I think that by enabling keep-alive, it will speed things up a bit. Am I right? Is this supported by Nginx? Is this a widely implemented feature in other software and hardware load balancers? What else besides HAProxy?

  • Data transfer is extrem slow after partitioning extern usb drive

    - by user125912
    I bought an extern usb 3.0 drive with 500 gb capacity. OS is Windows 7. I use it with an usb 2.0 slot, no prob. Initially I used it without making several partitions and it was fast as hell. Then I had the great idea to make partitions, one for programs, one for data and one for backup. I chose the free EASEUS Partition Master 9.1.1. and ended up with these partitions: F:Apps, primary, NTFS, 100gb H:Data, logic, NTFS, 250gb B:Backup, logic, NTFS, 150gb THE PROBLEM: When I copy files from C: to F: I get a transfer rate of about 100 KB/S ! When I copy files from C: to H: I get a transfer rate of about 4 MB/S ! thats all muuuch to slow, slower then before. What can I do to speed the shit up? Thanks in advance!

  • SSD RAID 5 or 10?

    - by Kyle
    I have a few extra SSD drives (I know its rare but this has actually happened). I figured since I have almost 500 GB in SSD's I might as well replace all of my standard HDD's with them. I currently have a RAID 5 setup and enjoy the the speed and redundancy with 10k RPM drives. Should I bother to put my SSD's in RAID 5? I have not heard of anyone doing this and have no idea how it is going to work out. The loss of space doesn't really bother me since I have a 2 TB NAS with all my media on it. Does anyone have experience with putting solid state drives in a RAID 5. If RAID 5 is a bad idea has anyone had experience with a RAID 10? is it possible to stripe the SSD's and provide redundancy with standard HDD's?

  • Tool to create unscaled call-out from a thumbnail image?

    - by Mal Ross
    I'm creating an online tutorial for some software and need to include screenshots. In particular, I want to highlight the position and appearance of a given control in a large screen. Given that I haven't got the space to show the screen at full resolution (at least, not alongside the tutorial text), I figured I would use a kind of call-out from a thumbnail. Here's my poor first effort, made in Paint.NET: Given how long this took me to craft, I'd really like to find a tool to speed things up (and make them look a little more professional!). Preferably a free one, too - or one that has a downloadable trial. The exact style it produces isn't that important, provided it achieves the desired effect. Can anyone help me out? Thanks, Mal. P.S. I'm using Windows Vista.

  • Why is there no 64-bit Linux Firefox build?

    - by Legooolas
    It seems that I have to build my own 64-bit Firefox for Linux, as Mozilla won't support it until Firefox 4. Why is this? It looks to me as though it works fine, although without some of the speed improvements to the Javascript engine which the 32-bit version gets. (Edit: Yes I could run the 32-bit version but I'm trying to keep my system clear of 32-bit cruft and libraries etc, and all the plug-ins worked fine in 3.0.11 64-bit unofficial builds.) Update : No longer relevant as Mozilla provide 64-bit builds, but they don't show them on the download pages of mozilla.org, just on the ftp site as mentioned in one of the answers below.

  • Booting a native Windows install in Virtualbox: is it possible?

    - by Aron Rotteveel
    I am looking for something similiar to Bootcamp. Currently, I run Ubuntu Maveric as my primary operating system and run Windows 7 in Virtualbox. For some tasks, however, running Windows virtualized just seems to result in too much overhead and speed loss, and I'd like to be able to boot natively. The ideal situation would be to setup Windows and Ubuntu in dual boot on seperate partitions, with the ability to boot the Windows partition in Virtualbox on Ubuntu as well. Is this possible? Also, how it is that Bootcamp seems to be the only system capable of this?

  • When should I use SATA 6gb/s?

    - by Gili
    I purchased a Baraccuda hard-drive (model ST3000DM001) that supports a maximum read transfer rate of 210 MB/s and SATA 1.5/3/6 Gb/s. My motherboard has a limited number of 6 Gb/s ports so I'd like to reserve them for when it's really necessary. When does a hard-drive benefit from a SATA 6 Gb/s port? Doesn't it require a transfer speed of at least 375 MB/s to surpass the limit of SATA 3 Gb/s? Are there any other benefits of SATA 6 Gb/s vs 3 Gb/s ports?

  • Is it preferable to use POP or IMAP to check multiple google mail accounts from one?

    - by Adam Tuttle
    I have email accounts on several domains that use Google Mail, and thus far I've only ever used POP to send and receive mail from a single inbox. This is quite functional, and as long as I remember to select the appropriate FROM address when starting a new thread, mostly works without any additional thought: messages received on account A are replied to via account A, and so on. My only complaint is the lag -- I've seen sometimes as much as a half hour between messages arriving in an inbox before being imported into my primary inbox via POP. My question is this: Google also supports IMAP. Would that be in any way preferable over POP access? Reduced lag would be nice, but not at a general speed cost, if everything I do has to check another mailbox too.

  • Good Choice of Memory for Asus K52F-BBR5

    - by Christopher Painter
    I recently purchased an Asus K52F-BBR5 notebook. It's a basic laptop with an Intel P6100 CPU and Mobile Intel® HM55 Express Chipset. It came with 3GB of DDR3 SODIMM memory and I'd like to expand it to 8GB. I'm a little confused by DDR3 nomenclature and not up to date on my knowledge of chipsets. I'd like to make a good choice when selecting memory for it. Crucial's database suggests using either a PC3-8500 with CAS 7 or a PC3-10600 with a CAS of 9. Is the 8500 better because of it's CAS 7 or will my chipset run the memory async at a higher speed and get better performance? Which would be a better choice for my chipset and CPU? Price difference is negligble.
