Since 2.6.38 ath9k has become slow as a snail. After searching this issue I have found a solution.
Create a file called /etc/modprobe.d/ath9.conf in this file enter thisoptions ath9k nohwcrypt=1Reboot or reload the module and enjoy high speed again.
I got a TP-Link WN951N Wireless-N PCI card for my Squeeze HTPC (this is AR5008. Performance is awful. On the lucky runs I'm getting 4 MB/s from Samba, most of the times I'm seeing 1-2 MB/s, and sometimes less than 1 MB/s. Also, ssh is not smooth, e.g. when I type commands, it can take seconds before text appears on the console, or I get slo-mo. Forcing 11g gets me a consistent 2.2 MB/s but lag is still there.
The machine has also been tested under XP SP3 and pulled off a solid 11 MB/s on a large file with no lag, so the hardware would seem OK. I've tried several kernel versions (both Liquorix and Debian stock), and a couple versions of compat-wireless (2.6.38-rc4 and 2011/03/03 bleeding edge), with little variation in outcomes. The logs got no weird messages in them, although with the more recent drivers/kernels iwconfig looks like this:
wlan0 IEEE 802.11bgn ESSID:"GuessIt" Mode:Managed Frequency:2.457 GHz Access Point: x:y:z:t:u:w Bit Rate=270 Mb/s Tx-Power=19 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=46/70 Signal level=-64 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:64 Invalid misc:19967 Missed beacon:0
Tx discarded packets are through the roof and excessive retries is not bad either. The system doesn't run NetworkManager, wicd or whatnot. All of the wireless is configured through /etc/network/interfaces: # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback
Since upgrading to Ubuntu 11.04 my wireless connection has been extremely slow. The same happened with 10.10. Although that was quite different. Back then everything within my network moved slowly, but now it doesn't affect my web browser. It seems to have only slowed the application centre and update manager. I am still waiting for the flash plugin to download and install for testing ....., but I am torrenting Ubuntu 11.04 right now and have actually hit the limit of my bandwidth (1.1 MB/s) whereas the speed in the software centre and update manager was in the region of 45 kb/s.
I'm not sure if this is because I have installed extra drivers found here after I did some research.
Although my web surfing is fast and stable, I would like to get my updates and applications downloading properly. Does anyone know what I can do?
From my 2-hour googling spree I know you may want the results from the command "lspci"
Code: root@Felicia:/home/silkworm# lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
I have a 500gB USB drive connected to my laptop for backups and filestorage. But I can't get it to play nice with Midnight Commander. My transfer speeds max ut at 2MB/s wich is painfully slow when moving large files such as movies. Worker FM transfers the same files to the same drive much MUCH faster (not sure by how much, though). This leads me to the conclusion that the problem lies with MC.
I am using debian(lenny) on a pc coexisting with windows. I use grub to decide which o/s to boot.
I picked debian, logged in as a regular user. I selected "Administration" under the "System" tab and then selected "Update Manager". I had to provide the root password.
I was asked to insert Binary DVD-1 and was told to use smart update. I did at which time 16 files begun downloading at between 4400 B/s and 4800 B/s from the Security server. It looks like it is downloading a new linux image.
Just re-installed Bodhi. Ran update, dist-update, set up connection and connection still slow or timing out and reporting errors in 'iwconfig'. This is 3rd re-install of this version. Have also tried 3.0 kernel and pae versions of Bodhi. Cannot get this connection up to speed and without errors. Atheros chipset ar9271.
Sorry for weird subject line and opening paragraph. Trying to make it easy to find and browse in case this gets solved and can help someone else. Not being a Linux guru, I can only hope to help others through my mistakes and ignorance.
I followed instructions to update driver listed at Linux Wireless.
In addition to following the directions at Linux Wireless, I also downloaded the GUI Program to install ath9k_htc.
No luck. My connection reports 1M/s and is reporting "invalid misc:" errors in iwconfig.
I'm running Midori browser but apt-get and wget are also downloading slowly.
I'm connecting to a Zyxel 660 series router using WPA/WPA2.
I mount a BD-RE in Debian Jessie to write about 20GB of data. But the writing speed is terrible slow. I get a Speed of 250kb/sec.
Are there any options to increase the speed of writing? I don't use packet writing and no wodim, no growisofs, nothing. I just mounted the disk and I use mc (Midnight commander) to copy the data.
I got a new machine with GA-p55A-ud3 mobo and a WDC WD10EARS 1T disk. When I tried to benchmark the disk IO, I was suprised by the low write speed:
[Children see throughput for 1 initial writers = 35962.63 KB/sec Parent sees throughput for 1 initial writers = 35962.63 KB/sec Min throughput per process = 35962.63 KB/sec
I'm experiencing very slow network speeds in one direction (out) on a clean install of debian.

I've tried with different cables on the server, no luck. Also note that the laptop gets full speed to speedtest.net as per my internet subscription (75/75 gbit fiber), so the laptop can be ruled out as a problem since it gets more than 75X performance to the internet compared to the local server.
The main purpose of this server is to be a virtualbox host. I've set up one guest system and ran iperf between the host/guest (bridged network). It gives better numbers, still the host -> guest direction is much slower than it should be:

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab
When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s
But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.
I am running Ubuntu 10.04 from a USB key (16GB). Overall I'm pretty fine with it but there are a few problems I am having. It seems to be very slow. In particular, Firefox and Pidgin freeze every now and then, before becoming active again. The same thing also happens for other applications such as Rhythmbox, Gedit, and the terminal. Additionally my start up and shut down times are horrible (worse than when I use Vista and Ubuntu 8.04). I was wondering if there is something with my install or if this is all due to the fact that I am running from a USB. I don't think it's the USB since I ran 8.04 from a USB HDD (55GB) and didn't have any problems with speed.
I'm using Fedora 13 x86_64. The internet speed is very very slow. I have enough hard disk space, RAM. Processor AMD Athlon II 2.6GHz. What can be the reasons?
I just installed Ubuntu 9.10, replacing Windows 7.
its running a little slower than I hoped it would, loading movies takes a while, and when i switch to full screen, it takes about 5 seconds to catch up.
im suspicious that my video card driver might not be configured correctly. can anyone tell me what I might need to configure to get things running smoother?
other things on the computer are also running slow, like opening Firefox, it takes a while for the window to appear.
I have been trying out Ubuntu One for the past couple of days but find it to be incredibly slow. At first i had put a folder will a large amount of images in the ubuntu one folder. The total size of it was 35Mb, after over 26 hours only 11,5Mb of that had been uploaded.
After looking around some on these forums i saw several comments about it being slow when it is a large amount of files, no matter if the filesize is small or large. I decided to try it out with a larger single file. I erased everything that was in the previous share and then put my testfile of 350Mb in the Ubuntu One folder.
After two hours of waiting i could still not see it on the U1 website so i decided to see how long it would take with dropbox and put a copy of that file in my dropbox folder as well. The file was uploaded correctly to dropbox in just a couple of minutes but it has still not been uploaded to the U1 website even though it has been 4-5 hours since i first put it in my U1 folder.
I need to transcript some recordings to a friend of mine. I woule like to have the sound playing slower than usual. Is it possibe on any Ubuntu (L. Lynx) anyway? How?
Does anyone know if the Yum fastestmirror plugin only makes decisions based on latency to pick the best host or does it measure bandwidth? On my laptop for the last few weeks I've been getting super slow yum updates (3.5kB/sec), when I force it to use the baseurl it runs as fast as I'd expect (160+KB/sec).
So the fastestmirror plugin doesn't seem to work unless maybe it's measuring latency as fast but the actual download speed is slow. If so, fastestmirror plugin should really take both into account.
I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).
My Specs are: CPU: AMD Duron (tm) processor 1.8GHz Graphics Card: NVIDIA GeForce 6200 Memory: 2GB RAM I'm using KDE.
I'm trying to transfer some files to my USB stick, and it's transferring at the most pitiful rate, around 200-400kb/s, occasionally shooting up to 1MB/s, but not for more than a few seconds.
I realize a lot of factors can play into this, so I'll try to provide as much detail as I can.
I'm using OpenSUSE 11.3, KDE 4.6 RC2, and a Corsair Mini Voyager 16GB. My motherboard is a Gigabyte EP45-DS3L.

Code:
Sometimes too, the transfer just stops all together. It just... doesn't transfer for a while, then it'll go back to 400kb/s etc, then it'll stop again for a minute.
When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk. Is canonical blacklisting/slow listing my ip?
I am behind a university network but am sure this problem occurs at home .I did a clean install and had no problem until about an hour ago. When I tried to re download a project using bzr my speed instantly ropped.I had downloaded it fine a couple of hours ago. I hope that someone can shine some light on this, its very hard to work on projects if I can't download them.
I have a HP nx7400 laptop. Now I have a docking station DC power adapter - Works Fine. Ordered another DC so i could travel with it, but when used ubuntu runs at a very slow speed.
I have very suboptimal Internet speed in Wifi with Ubuntu. Normally in WIndows 7 I get download speeds up to 800 KB/s and a very fast Wifi experience, but in Ubuntu I get 100KB/s maximum and web page load speed is very extremely slow. Also, pinging to AP often gives very high response times and a lot of lost packages while in Windows they are very low and none packages are lost. I have a Netgear wg111v3 which worked out of box when I installed Ubuntu but always with this problem. It is updated and I've reinstalled Ubuntu many times..
Also I forgot to say that in Ubuntu the connection goes down very often and sometimes will not connect again until I reboot. Again in Windows never happened that. Motherboard: GA-MA74GM-S2H CPU: AMD Athlon 64X2 dual core 2 GB RAM Ubuntu 10.10 64 bit Wireless adapter Netgear wg111v3 USB .....
We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.
I am currently using fedora 12. My question is why is the speed for my yum and rpm are very slow. Something like Flash Player 10 couldn't even load after being installed. If I downloaded the rpm, the speed is like normal but if I yum it. The ESA took like >1,000,000 sec..or whatever..The point is it does seem like something has happened to my yum/rpm function. I can download and surf the web as usual. I just can't get any add-on such as the Flash Player 10. I can only use the basic already provided by Fedora.
I tried: su - yum clean all rpm --rebuilddb yum update but I am still unsure what type of RPM issue I am facing.
I am experiencing very slow speed with the Intel 5300AGN on a Dell Studio XPS notebook and the iwlagn driver. I'm using Fedora 12 with all the latest updates available. When connecting to a G network with WPA2 security, everything goes fine at "normal" speed. When connecting to a N network with WPA2 security, the download speed falls between 0 k/s and 20 k/s max. The connection speed (as stated by Network Manager and iwconfig) is between 0 kb/s (?) and 11 Mb/s during the same session. I'm can't connect through ssh or download with scp (stalled). Web pages take a lot of time to render.
When connecting to the same N network on Window 7, everything runs fine enough. Every N network I try is the same story. Works fine on windows, badly on F12..
I am having a very weird problem, of which I have never heard before. The problem, shortly (I will give details in the following), is that the copy speed between the partition in which I am running my Fedora and another partition where I store backup data is 50K/s, which is extremely slow (it has been usually around 10M/s, almost 200 times faster).
My laptop is a HP Pavillion Dv7 2080 ep, in which I have two disks of 250G. One of the disks is partitioned between two operational systems, Fedora 14 64 and Windows 7 64, and the other disk contains the above referred partition where I store my backups (lets call it backup disk). The problem happens ONLY when I try to copy anything from my home in Fedora to the backup disk. I first thought it could be a problem in the backup disk. Then I login into the windows and made a copy of some AVI files (3G approx) to the backup disk, which went normally, within a few seconds, thus eliminating this possibility. I try therefore to make the inverse process, a copy from the backup disk into my home folder in Fedora. It went normally, copying 4 G also within few seconds, actually with an excellent speed of 50M/s. After searching in google, I saw some people also complaining of slow copy speed (although they had 7M/s, more than 100 times faster than what I have now), and one cause could be that the source file system (in my case the Fedora home folder) would be near its full capacity. I therefore eliminate everything that I could, around 15G, and now I have like 20G of free disk space, which I think is more than enough for everything. However, the problem persists. Some people also said that it could be the type of files and/or amount of data. I therefore tried several kinds of files (from raw data files to AVI and RMVB regular video files), and several amounts of data (from single files with a few Megas to folders with 20G) and in all cases I had the same unacceptably low copy speed of 50K/s.
It seems to be a problem in the software, caused by the updates, since until 10 days ago it was everything ok. However, I usually make the updates whenever they appear but make my backups much less frequently. Therefore I don't know for sure what has changed in Fedora through the updates since the last backup I made, when everything was working fine.
I am having problems with website load speeds. I have fendora 15 and windows loaded on my machine. When I am in windows the internet connection is fine but when I am in fedora everything is slow. I am connecting wirelessly to a netgear router using a D-Link DWA-552 XtremeN Desktop Adapter
I have not installed anything for the wireless card.
I have tested my speeds from here [url] and I know that I am getting around 7000kb down.
I have gone into firefox to about:config and set network.dns.disableIPv6 to true... but everything is slow.
What can I do to speed up the start-up after login?
I am running OpenSuse 11.3 with Gnome on my laptop (Acer Travelmate 2490) and I need about two and a half minutes from login until the hard disk lamp 'settles down'. This is much longer than I have been used to expect from earlier OpenSus versions. Are there some default applications/processes I could ditch?
