  • Internet connection slower than network connection speed

    - by Mike Pateras
    I've got a computer connected to a wireless router on a different floor. When I look at the network connection, I'm told the signal strength is low, and that I've got a connection of about 26mbps (often higher). However, my internet connection on that machine is very slow. Speedtests show it at about 1-2mbps, and it really shows when loading pages and video. I have fiber optic internet access, and the machine that's connected to the router/modem via cable gets the 20mbps on speed tests, and is extremely fast in every day use. My question is, is the advertised 26mbps+ connection speed perhaps inaccurate, and that my wireless bandwidth is the likely bottleneck here? Or is the signal strength what's key here? And what might I do about this? Power cycling the router helped a bit, a speed test went as high as 6mbps after doing that.

  • How to determine the used size of device associated's buffer

    - by dubbaluga
    Hi, when mounting a device without the "sync" option, e. g. by invoking the following: mount -o async /dev/sdc1 /mnt a buffer is associated with a device to optimize (speed) read/write operations. Is there a way to determine the size of this buffer? Another question that comes into my mind is, if it's possible to find out how much of it is used currently. This can be interesting to determine the time it would take to "sync" or "umount" slow devices, such as flash-based media. Thanks in advance for your answers, Rainer

  • TightVNC (or any VNC) viewer windows scaling

    - by mr.b
    Hi, I am currently using TightVNC to connect to multiple remote hosts in LAN. I start 16 VNC viewers, set Scaling by: Auto (in connection options display), and then select all viewer windows and use Tile Horizontally, which covers my entire screen with VNC viewers. It all works sort of nice, except that desktop interaction is really slow when there are more then 4 VNC viewers. My question is, does VNC client (not just TightVNC, but any compatible client) support some kind of smart scaling option, so that client tells server something along the lines of: "Okay, I'm displaying your entire screen in a window size 300x225 px, so can you please start sending encoded images on that resolution?", at which point interactiveness of open connections dramatically increase, and when I decide to go full screen on some connection, client and server re-negotiate and server starts sending full resolution images again? Thanks!!

  • Simultaneous read/write to RAID array slows server to a crawl

    - by Jeff Leyser
    Fairly beefy NFS/SMB server (32GB RAM, 2 Xeon quad cores) with LSI MegaRAID 8888ELP controlling 12 drives configured into 3 different arrays. 5 2TB drives are grouped into a RAID 6 array. As expected, write performance to the array is slow. However, sustained, simultaneous read/write to the array (wether through NFS or done locally) seems to practically block any other access to anything else on the controller. For example, if I do: cp /home/joe/BigFile /home/joe/BigFileCopy where BigFile is 20G, then even a simple ls /home/jane will take many 10s of seconds to complete. In addition, an ls /backup will also take many tens of seconds, even though /backup is a different array on the same controller. As soon as the cp is done, everything is back to normal. cp /home/joe/BigFile /backup/BigFile does not exhibit this behavior. It's only when doing read/write to the same array.

  • renaming hard drives (sdc to sdb) on the fly

    - by w00t
    ata2: link is slow to respond, please be patient (ready=0) kernel: [2761026.198796] ata2: soft resetting link kernel: [2761031.226669] ata2.00: disabled kernel: [2761031.226720] ata2: EH complete kernel: [2761031.226753] sd 1:0:0:0: [sdb] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK,SUGGEST_OK After receiving the error above, I couldn't access /dev/sdb anymore. Not wanting to restart the server, I rescanned for the device using echo "- - -" > /sys/class/scsi_host/host1/scan and it readded the drive as /dev/sdc. From what I have found, I need to use echo "scsi add-single-device 0 0 3 0" > /proc/scsi/scsi, "3" being the SCSI ID which corresponds to sdb. Everything nice up to the point I execute the command and get -bash: echo: write error: Invalid argument. All the solutions point to using this method, but I am unable to. Any other method available?

  • Disk Response Time in Windows 7 Resource Monitor?

    - by Keith Nicholas
    In the resource monitor I'am looking at the disk response time. There are a lot of processes where the response time is thousands of milliseconds consistently, I'm pretty sure this is the source of my computer slowing down. I'm not sure what normal response times are though? I'm running win 7 64bit ultimate. This is running on a new computer, i5 with a terabyte drive, 4gigs of ram, etc, disk is still pretty much empty, so it should all be pretty snappy. And if it is going really slow, how do I track down whats causing it? I've turned off things like real time virus protection as experiments to see if there is something weird there, but makes no real difference (other than it doesn't contribute to the problem by accessing the disk)

  • Simple Workstation Imaging Solution?

    - by Will
    Hey guys, I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • How to optimize sandboxie for faster application loading

    - by user23950
    I'm referring to this one: http://www.sandboxie.com/index.php?DownloadSandboxie Do you know of any alternatives that might be better than this software. And if you don't know of any alternative. Can you show me how can I make it faster to load firefox. Or any other browser. Because it really makes application incredibly slow at loading when you run them inside a sandbox. I've also seen lots from here: http://superuser.com/questions/57129/alternative-to-sandboxie-for-64-bit-systems Do you know of any other?

  • Debian Server Daemon: File sync

    - by Gehk
    Hello, I'm looking for a way to (auto) sync files on some pcs over the internet and save/backup them on my server. Just like Dropbox and other services like that. I found iFolder (by Novell), but it's not made for debian (i think it would still compile). I don't know if it's made for an webserver or just home server. Another way would be FTP, I don't know clients (i use ubuntu and windows on my pcs), which autoupload new/edited files. There is also svn/csv, but they are quite slow (afaik), and I don't know if there are suited for this. Someone got an idea? Thanks.

  • RAID0 array of USB 2 disks, both connected to a single hub. Any benefit?

    - by Josh
    I have two unused USB 2 drives. I wanted to stripe them in a RAID0 configuration for fast disk access for virtual machines. (I find running a VMware virtual machine off a USB2 drive to be painfully slow. Especially Windows Vista) If I have both USB drives attached to the same USB2 hub, will that negate any benefit I gain by creating a RAID0 array? That is to say, is the speed of USB2 the limiting factor or is the speed of the drives? Would I get better performance by attaching one or both drives directly to my computer?

  • Photoshop CS4 slowing down, need advice to improve speed.

    - by Pennf0lio
    Hi, I just recently experienced problem with my Photoshop, It seem that it is slowing down when I am doing graphics design. Big or small files ( from 20 x 20 inch 300 dpi of resolution to 800x600 72 resolution ) it is really slowing down. Particularly when I am panning to my project It just get stuck for a few seconds then back to normal with slow movement. Can you guess what's wrong? I have an updated antivirus and I don't think virus is causing it. other adobe suite is working fine just my photoshop. I am running in windows 7, using Intel Core2 Duo 2.40 Ghz and has an Installed Ram of 2 GB. My primary scratch disk has 21 Gigabyte left and the secondary has a 13.89 GB. I need a solution urgently. I am planning to reformat my computer just to resolve my problem.

  • Is an Intel Atom D525 suitable to run MythTV

    - by Martin Thompson
    I have an oldish netbook with an Atom N450 (1.6GHz, 512KB cache) - I've been using it to experiment with MythTV, but it seems really slow, even just to work through the menus! Seconds, sometimes 10 or 20s, to load a new menu. Admittedly from a remote backend, but my older Core1 based laptop seems to be fine with the same setup. I was hoping to use one of the so-called "nettop" devices which currently seem to be D525-based (1.8GHz, 1MB cache) - is double the cache really going to make that much difference? Or has the internal architecture of the Atom moved on leaps and bounds in between? Given that I design non-Intel embedded computers for a living I was hoping to get lots of hardcore architecture detail from the Intel website, so I could see for myself, but I can't find it! So: will a D525 be fast enough to run a MythTV backend/frontend combined box?

  • Freeware Local Proxy for Proxy Chaining with HTTPAUTH

    - by pepoluan
    I am looking for a freeware local proxy to perform proxy-chaining with HTTPAUTH. To explain my situation: In my workplace I am forced to keep switching between several internet-connected apps, and thus everytime I have to type in the credentials (or, at least, click on 'OK' to send my previously-saved credential). To make matters more annoying, the proxy login times out every 30 minutes, requiring me to lather-rinse-repeat the whole annoyance. I'd like to just point them all to a locally installed proxy which will on its own perform the required HTTPAUTH against the corporate proxy. I've tried Cntlm, but it always fail to authenticate (and according to this thread, that is due to the proxy using HTTPAUTH which is not supported by Cntlm) Any suggestions? ETA: I found Polipo, but it's kinda wonky on Windows. Especially if I visit a new URL, and the DNS server is a bit slow, then Polipo will simply drop/refuse the connection. And I have to put my password in plaintext. If there's a better suggestion, I'm all ears.

  • Firefox being really sluggish on php.net website?

    - by Rory
    Is it just me, or is firefox (3.5 on Ubuntu 9.10 karmic) really sluggish when opening the PHP.net website? When I have several tabs open with just the PHP.net website, and I tab up and down (with Control-PageUp/Down), it's slow to change tab. If I do it quickly, then firefox freezes for a few seconds (I know because it goes grey, which is a compiz feature to show unresponsive windows). The CPU usage also goes up when I'm tabbing to PHP.net pages. UPDATE: This appears to happen for all PHP.net webpages. For other pages, on other sites, Firefox is fine (for me).

  • Strange DNS problem [seems to be IPv6 issue]

    - by Homer J. Simpson
    Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • Removing virus on Windows XP

    Hi, What is the best way to remove viruses from a Windows machine? Forgot to write down the message, but how I know there was a virus was because my wallpaper was changed to "You have been hacked" or something like that. I've tried reinstalling the OS several times but that doesn't seem to help. Somehow the virus still seems to be there. (i.e machine is slow and some unknown exe is always trying to access the internet). The exe name is something like ,,,,55786. Please enlight. Thanks, Tee

  • Comparison between these video cards?

    - by seedeg
    Currently I have a GeForce 8600GT as a video card. I started playing EVE online and it is not that smooth (Apart from the fact that my Windows 7 is starting to become slow so it needs a format). Now I have these 3 video cards on my mind: 1GB Gainward GF GT240 PCI-Express Video Card 1GB Gainward GF9800GT PCI-Express Video Card 1GB Gainward GF GT240-GS PCI-Express Video Card I tried comparing them from nvidia's site: HelpMeChoose but the GT240-GS is not available for comparison. However, when I tried comparing the GT240 with the 9800GT, the latter was the winner. You must keep in consideration that the cheapest one is the GT2400. The 9800GT is in the middle, and the one which is not available for comparison, the GT240-GS is the most expensive one (about 6 euros more than the 9800GT). Is the GT240-GS the best video card from these? Thanks in advance for your responses.

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

  • How to do simple multitasked loop processing over filenames with PowerShell?

    - by Ville Koskinen
    I'm batch transcoding some 50 GB of video files on a USB hard disk which is connected to a wlan router. The drive is mapped as a network drive on my Windows 7 laptop. The speed handicap of the wlan causes some parts of the processing to become unnecessarily slow, so I would like to do the following with PowerShell: List the names of the files on the network drive to be transcoded Copy the first file to a temporary folder on my laptop Simultaneously Transcode the file in the folder Begin copying the next file from the network drive to the temporary folder After transcoding and copy have both ended, Delete the file which has been transcoded from the temporary folder Begin transcoding next file in the temporary folder Loop until all files have been processed How would I be able to do this with PowerShell? The multitasking part is an obstacle for my skill/persistence combination.

  • back-end SQL server 2005 databases for website

    - by Datapimp23
    Hi, We're migrating an existing IIS website + MS SQL 2005 database (on the same server) to a new test set-up. The existing set-up is too slow. I want one ISS server and 2 X MS SQL server 2005. One live DB server for the website queries (inserts, updates) and another for backups, reports or stored procedures. So the live DB should be more aimed at performance. The other doesn't even need to be synced instantly. What is the best way in SQL server 2005 to set this up. Can somebody point me in the right direction and give me some pointers. Thanks

  • Streaming Flash Video - getting my feet wet

    - by Travis
    I'm working on a project that will involve having a couple thousand short videos online. I haven't done anything with online video before and this is all a bit new to me, so I am looking for some general advice... I would like to use Flowplayer, and I would like to encode the videos as H264s. I am enamoured with Flowplayer's slow motion feature, which if I understand correctly, is only available using a Wowza server. I'm wondering: Is it advisable to use a delivery network of some sort? (Flowplayer seems to have a partnership with HDDN, and recommends them. http://www.hddn.com/) Or would I be better off purchasing Wowza and installing it on our own server? (At first glance, it looks as though signing up with a network like HDDN is much simpler, but perhaps there are problems that come along with this...?) Any tips / warnings of imminent peril would be much appreciated. Thanks in advance.

  • Configuration of Sonicwall Load Balancing

    - by jacke672
    We installed a Sonicwall NSA 240 appliance and have configured it up for our SSL VPN connection and for load balancing with 2 ADSL lines. Over the past week, I have been testing the load balancing options to optimize the connection speeds for our users - but I've run into the following: Round Robin load balancing is the ideal load balancing setting and it's roughly doubling our throughput- but, when it's active users are unable to access any SSL enabled websites such as banking, web-mail, etc. For this reason, I have been using percentage based balancing as it allows me to enable source and destination IP binding, which doesn't 'break' any secure connections but were left with the slow connection speeds we had before adding the second line. I'm looking for a method in which we can take advantage of the round robin connection speeds while allowing users to access sites with SSL certificates, all while still allowing our remote (vpn) users to connect. Any help would be appreciated. Thanks

  • Could a too low voltage during long periods damage my computer fan?

    - by Sopalajo de Arrierez
    Computer fans use to run at 12Volt, but most as for today they allow 9Volt or even less to slow down the fan speed (RPM, Revolutions Per Minute). In cases of too low voltage, the fan stops, but I can see it "trying to start again". For example: my Tacens 9dB fan stops at about 10 Volts, but to start it again, 10.5Volt is not enough, and the engine tries to move the fan (I can see a small movement as an "attempt" to move) each 1-5 seconds, but it does not succees, so the fan keeps at 0 RPM. Maybe that "attempt" to move could damage the internal engine of the fan when it last for hours or days?

  • Moving MS Exchange 2007 to another machine

    - by Mustafa Ismail Mustafa
    We have a machine that has been chugging along with the burden of both Exchange and DC and DNS all with SBS 2008. We have a better machine now and I'd like to move Exchange 2007 to that machine and take it off of this machine. In fact, I'm planning on formatting the old machine and get rid of SBS all together because it is making the machine SLOW. How would I go about making the move? I've read on previous versions of Exchange (2000), that all you do is install Exchange on the new machine and then start moving mailboxes one after the other. Well, what about all the different rules we have in place? How do those get moved? How do we de-commission the old exchange and set up the new exchange as the primary one? Come to think of it, how do we have both exchanges recognize each other on the same domain? TIA
