Ubuntu :: Network Slowdown After Last 10.04 Update?
Jul 3, 2010
Anyone seeing a dramatic slowdown and "PAGE NOT FOUNDS" after the latest updates?
It even happens on LAN activity. Peak speed is excellent, the ability to resolve both local and WAN addresses is very spotty.
Machine is a newer Clone with AMD Phenom II dual core with 2gb running 10.04 32-bit with Gnome. Network is Gigabyte MoBo 1000-T ethernet hardwired to Dlink router into cablemodem.
XP and Win7 aren't affected.
It was ripping this morning, but right now, is pretty much crippled.

I have a home server based on Ubuntu Linux 10.04.2.
Hardware:
Motherboard - Asus AT4NM10-I (Intel NM10, PCI)
CPU - Integrated Intel Atom D410
RAM - 2 Gb
Lan - D-Link DGE-528T Gigabit Adapter
Provider gives 8/2 Mbit ADSL connection.
So tried Deluge and Transmission, and integrated or external network card and no luck.
When torrent file is being seeded on top speed network starts freezing, server almost unreachable, video freezing when watching it by LAN from server... etc...
When I pause upload - everything starts working ok!
Network based on gigabit switch and cooper UTP cables...

i recently caved and upgraded to ubuntu 11.04, despite my hate of the unity interface. anyway, i seem to be having completely random, massive lag spikes! seems to happen when i do certain things, such as spend to much time on videos, or stream hd videos. playing games, such as minecraft, and using skype seems to be giving me the same issue. i don't know what to do! i haven't found anything similar to this in my google searches,

I am having a bad slowdown issue when I enable Visual Effects with the Ati proprietary drivers that come with the installation. Everything runs very slow maximizing and minimizing take about 3-5 seconds per click and the effects get all choppy and don't look right like they did on my x1950 video card. I have tried downloading the current drivers from the ATI site but they don't seem to be initialising correctly after I perform the install.
I also know that the graphics card is not the culprit as it works perfectly fine on my Windows 7 64 bit install. There is no reason that my video card cannot handle the Visual Effects as it is a 1GB 4890 should have more than enough horsepower.
My machine is:
AMD Phenom II 965 Black Edition
8 GB G. Skill 1600 DDR3 Memory
1 TB Western Digital Caviar hard drive
1 GB 4890 Graphics Card ATI.

I have Ubuntu 10.04. I installed the KDE libraries to use Okular. Then Ubuntu took almost 30s more to boot (20s black screen between login and desktop). I uninstalled KDE, booted on another kernel, rebooted and the boot time was OK again (25s).
I reinstalled KDE, 55s to boot again. Rebooted couples of times always the same. Rebooted on another kernel then again on mine (it seems to fix the slow boot times).
Boot time was 35s (I thought it was OK). After lauching Okular, the boot time was again 55s...
Removed KDE, Okular, and the boot time is normal again since 10 reboots..

Does anyone else have problems when loading an animated gif in firefox? After upgrading to natty, firefox eats 100% of cpu each time an animated gif is displayed on the tab title, or when the favicon is an animation. I have an fglrx driver, but opengl animation doesnt slowdown pc as much as favicons does on firefox.

I've made a simple headless home server based on:
1. Motherboard Asus AT4NM10-I (Intel NM10, PCI)
2. CPU integrated Intel Atom D410
3. 2 Gb of RAM
4. Network Card D-Link DGE-528T 10/100/1000 Mbit/s
5. OS Ubuntu Server 10.04.2 (All installed packages are up to date)
Storage build under LVM based on:
1. Samsung HD103SI - 1 Tb, 5400/32 Mb.
2. Hitachi SATA 2000Gb Deskstar 7K3000 - 2 Tb, 7200/64 Mb.
So found one issue: When torrent upload speed reaches peak speed (160-200 Kbytes/s) huge read slowdown happens. Server becomes almost unreachable... It allows to connect via putty but it takes a lot of time.
Tested top stats during those lags (Deluge, Transmission) - 10-15% CPU usage.
So I think the problem is in LVM and not in CPU.
How is it possible to find weak place in system to avoid those lags... Cause if torrent is seeding it's impossible to watch movies through network form that server.

I have noticed that when iptables is active on my router i get a noticeable slowdown on browsing. This is untraceable through traceroute:
Code:
traceroute -n www.a-site-here.com
finishes immediately and at the same time when loading the site on firefox I am getting timeouts.
I use firewall builder to configure iptables. I have removed all rules while trying to find the one causing the problem, but even disabling all rules does not solve the problem. So, by leaving only an "accept-all" rule on firewall builder(so i don't lock myself outside) I still get slowdowns. In this case
Code:
iptables --list-rules
gives:
Code:
-P INPUT DROP
-P FORWARD DROP
-P OUTPUT DROP

Does anyone else find that Openoffice 3.2's spreadsheet app becomes unresponsive when copying and pasting multi-cell selections? I've had this problem ever since I started using Ubuntu 10.04, which comes with OO.O 3.2. The problem becomes noticeable whenever I make a selection more than about 8-10 columns across. Once the flashing border appears around the selected cells, the spreadsheet app becomes very sluggish. The mouse still moves normally, but it takes several seconds after a click until the highlight moves to another cell, or to un-select the cells, or copy them. These slowdowns happen both in old spreadsheets and in freshly created ones. They didn't happen with Openoffice 3.1 or earlier. Haven't tried it under Windows, so I'm not sure whether this is an issue specific to Linux OpenOffice 3.2. Other apps don't seem to be affected.

If I initiate a file copy of more than a couple of GiB, the PC goes into a dramatic slowdown. Even selecting a different subdirectory through Nautilus can take 30+ seconds.Now, whilst I appreciate that file copying puts a load on the bus, DMA and, to a certain extent, the CPU, it seems unconscionable that it makes the PC effectively unusable until the copy has completed.Is there any way to (practically) lower the priority, or similar, of the copy process so that one can continue to use the platform during large file copies? Right now, I end up using a laptop adjacent to the PC whenever I have to copy a large file. This, for a mainstream operating system is, frankly, ludicrous.I'm aware that I could run Nautilus 'nicely' but I don't want to make changes which would compromise other aspects of the system. It would also be pleasant, for a change, not to have to read a couple of telephone directories of technical documentation in order to resolve the problem myself. This must be a general problem and, in my view, something which seriously compromises the usefulness of Ubuntu given the sizes of contemporary drives and files.
The i7 I'm using at the moment has 8 cores non of which go over 15% usage while the copy is progressing despite the OS being effectively frozen for long periods.Environment:Intel Core i7-2600 @ 3.40GHz; 16GB RAM; Natty (11.04) fully updated as at 29th July 2011; Kernel 2.6.38-10-generic, GNOME 2.32.1.; Primary drive has 563.9GiB free space, Running in Ubuntu 'Classic' (no effects) mode
Disk /dev/sdc: 2000.4 GB, 2000398934016 bytes

This is not the common problem that's on the stickied thread. I'm able to connect to my wireless network perfectly. I switch between Windows to game and Linux for desktop, coding, and hosting, so I can tell it has something to do with ubuntu 10.10. When I'm connected to my wireless network, at random times, my internet begins to slowdown, then I get disconnected from the internet, but the taskbar says I'm connected. This problem only happens in ubuntu and not Windows for some strange reason.
The applications that are usually open do not cause it, because it still does it even though I have little applications open (Google Chrome, gedit). When I'm on Teamspeak 3, I notice my ping rises to the 1000s randomly, and I get disconnected. Once again that only happens on Ubuntu.

I'm running 32-bit Debian Squeeze (2.6.32-5-686) on an old IBM TinkCentre piece-meal system that runs great otherwise. I have a LITEON iHAS424 Burner attached. As soon as I insert any disk (CD, DVD, Blank, Commercial, etc.) the system either locks up entirely or crawls to a near stop. The drive is about 3-4 months old and I've experienced the problem a couple of times in the past but just about every time I try to use it lately. The CD/DVD drive seems to work fine on other systems, but I haven't had the luxury of leaving in for any length of time to be 100% sure.
I have been able to pull out of the problem in the past by opening up the case and disconnecting/reconnecting both ends of the drive cable, but this doesn't always work and never "feels right" as a fix.Here is what I think are the significant portions of my messages log file:Quote:

I recently added an external hard drive through a IEEE 1394 interface. I'm finding that during large file transfers the system slows to a crawl. It's still running: routing for example seems fine. But running applications are pretty much unusable: Apache is unusably slow, SSH login is very slow, etc. Currently I'm using the IEEE 1394 drivers from Axel's ATRpms but I'm pretty sure I saw this with the default kernel IEEE 1394 drivers too.

I'm running a Geforce FX 5900 Ultra with nvidias 173.14.27 driver. I'm running slackware 13.1 with kernel 2.6.35.5.
I get a horrible slowdown which is noticeable in emulators such as bsnes and kega fusion. I also think it's responsible for other issues that involve zsnes flickering like mad and hanging. Zsnes will actually crash if I select any filter plugins with opengl output modes.
Kega Fusion slows down to a crawl (we're talking 10 fps) immediately before loading a rom. Playing a rom makes it even slower.
Bsnes has the same kinda slowdown as kega fusion (even worse since it's so cpu intensive) when I activate scanlines or any type of output filter with opengl. Otherwise with no filters and just plain opengl it seems to run fast like it should...
Gens-GS doesn't seem to enable any filters in fullscreen mode... They work however in windowed mode with no slowdown issues...
I've compiled and installed SDL 1.3 from hg repository, then recompiled bsnes just to test it with newer SDL. Unfortunately the problem persists even with a newer SDL version which thankfully for me means I can revert to the older stock SDL without having to recompile everything else haha!
It's funny because I thought these issues were related to the emulators and not the video card drivers. I had these issues for a couple years running ubuntu and trying other distros. When I installed Slackware 13.1 I decided to try my Radeon 9700 pro and kega fusion no longer had this slowdown issue! I switched back to my Geforce and installed nvidia's drivers and immediately had slowdown issues... I'm gonna switch back to the radeon card and test the other emulators but otherwise it'd be nice to know if there's a solution to this issue...
Ok I installed my radeon card: nvidia-installer --uninstall, then updated xf86-video-ati from 6.13.0 to 6.13.2. Even though kega fusion runs fine I get even worse problems with everything else! LOL so I'm going back to my geforce card.

I have configured OpenSuSE 11.1 in VirtualBox and Networking was working fine and I was able to access network. Yesterday I recieved update notification from SuSE and updated machine. Now after restart eth0 is not comming up. In Hardware profile I can see Network Card but it is not configured automatically. I don't know how to configure it. Virtualbox Networking was working before latest update and just tried in other virtual machines.

I'm usually on 8.04, which I like to keep up to date. This morning, after downloading and installing the latest automatic update, the system refuses to recognise that I have any kind of network connection. I know it's not the hardware, as I'm reporting this on the same machine booted as something else. Is it possible to 'undo' recent updates ? and, if so, how ?

I used Ubuntu for the first time yesterday (V.9.04) and imediatly upgrade it to V.9.10. After,the DSL conection failed to conect. After reading many threads here I was able to connect by opening a terminal:
sudo pon dsl-provider
It seems ther's a bug with network-manager, but I'd like to use it again as it easier and NB user-friendly.

I'm running VBOX OSE and wanted to access files on my native machine (ubuntu 9.10) from my virtual machine (Windows XP professional)
Now, I can ping the native host from the XP box, but can't access the share.
I have tried re-sharing the directory but it won't work.
Another interesting aspect is that I can't access the VBOX either. It gives me the error:
"Error: Failed to retrieve share list from server Please select another viewer and try again."
Up until this morning it worked just fine.
Unfortunately I didn't pay attention which software was updated during the process.

I installed 10.04 yesterday. The computer had an MS OS on it but I chose to format the entire HD for Ubuntu. The install seemed to go fine. When logged in there were updates available, and I installed all of them. After a reboot I tried getting on the internet and found that my network was 'disconnected'. I've checked the cabling, and that the LAN is still enabled in the BIOS. I assume the network had to have been functioning to do the original update. How do I figure out what changed. I've been reading the network section of a Linux book and came up with a little data that might help. My hardware is listed after the host file.
$ ifconfig

I upgraded my desktop from 9.10 to 10.04. The updated system works without problem - except that apt-get/Update Manager/Synamptic does not connect to the net anymore.
When I try to check for updates with the update manager, I get the message below. I have set different servers with the same result, and checked if there is a proxy set up somewhere, which is not. I also tried apt-get with the fix flag.
When I access the uri's with a browser, that works without a problem.
Message from update manager:

Using Ubuntu 10.04 (2.6.32-31)on a Dell studio today.Update manager offered four updates, one about networking. I accepted. After restart the Network-Manager icon had vanished from the tool bar and was replaced by a second loudspeaker control icon. No ability to link to the internet. Starting Network-Manager from the pull-down menus did not help.Muggins Noob thought, un/re-install Network Manager. Duh! Uninstall is fine, but re-installing from the web without Network-Manager, tricky. Sadly no ethernet wire available, either wifi or GSM/3G.

When I ran updates and installed 9.10, this message appeared, "Network service discovery disabled. Your current network has a .local domain, which is not recommended and incompatible with the Avahi network service discovery. The service has been disabled." The computer will not respond to anything, completely frozen--I am not able to open any programs and the CPU itself seems to be running loudly.
