Networking :: LAN Is Running Much Slower
May 15, 2011
I am doing backups and restores to and from a backup server machine in the garage (in case of fire or theft) using rsync, and the LAN is running much slower than I think it should. Best consistent speed I get is 40Mb/s. The lights on the interface cards indicate it's in Gb mode, and the interfaces are fairly new. The router is a Netgear WNDR3700 the top-of-the-line consumer-grade router. Hardwire only, using Ubiquiti ToughCable and ToughConnectors, less than a 50' run.

Im experiencing a strange problem with 10.04. When it first boots up its reasonably quick (as snappy as Gnome ever has been) but after its been running for a day or two it gets ununsably slow and has to be rebooted.
I dont see how it can be anything to do with my hardware as it runs OK when first started. Ive monitored RAM usage and it doesnt seem to differ much. There's always the same amount unused.

I am comparing distros of Linux on a computer with VERY low specs. I have a CLI only version of Ubuntu 9.10 running A-OK, but when I run lwm or just X the video flickers (which I believe is due not to the video card/driver but to the resources used). I have tried this with two video cards with the same result.
When I run puppy it flies with no setup.
I know that Puppy is designed for older systems (2.4 Kernel and all that), but is there any other reason why Ubuntu would be slow in comparison.
I am using the nv driver with a Riva TNT PCI Video card.

I've found myself using the -v flag for lots of applications less and less (especially for trivial stuff like tar and cp). However, when I did and I was, say, unzipping a large file, it would take longer than when I didn't use the -v flag.I assume this is because the terminal has to process the text and I'm filling up whatever buffer it might have. But my question is, does this make the application actually run slower or does it complete in the same amount of time and what I'm seeing is the terminal trying to catch up?

I just reinstalled my OS (Ubuntu 10.04) and on a new and faster drive than before. And now it's running slower! I was an IDE drive before and not it's SATA and at higher RPM's. The first thing I noticed was that my game, "Armagetron" was not the same. The graphics are really screwed up in it. It looks like a diff version altogether! And I can't find any other versions. Also the controls were different! I have never had to change the controls before. This is what it use to look like before the format: [URL]. This is what it looks like now: Then I played some other games just to see and test. They don't look different but they definitely LAG.....

Debian lenny, old install (I've upgraded to lenny when it was just about to become the stable release), versus windows 7, fresh install.Comparing browsers speeds with numion.com/Stopwatch.html, I had results such as:Iceweasel (firefox) on linux: from 9.154 seconds to 21:860 seconds (the same webpage, reloaded)Firefox on windows: 4.32 seconds - and never much slower than thatThe fastest browser on linux was Opera, ranging from 8.562 to 5.503 secs to load the same page, but even internet explorer beat/match it with its timing of about five seconds.
I have not other browsers on windows; on linux there is aroraonqueror (KDE3), kazehakase, chrome, and dillo, besides text browsers. I didn't test on dillo; Kazehakase and chrome were the only ones which had nearly decent results, but still very bad, 11 to 13 seconds for chrome, and 21 for kazehakase. Konqueror just seemed to never finish to load the page, I gave up when it was still loading somethingfter nutes and 5 seconds.'ve emptied the cache every time I would test, and I was running almost only the browsers and not much else. Whatever comes by default on windows, and on linux, I was on openbox, with nothing much going on I guess, I think the most memory consuming processthe time, besides xorg and the browsers themselves, was dictd.
I've researched a little bit about, but not enough to make a list of possible things to change in order to improve the speed on linux. Most of the time there are people just agreeing that on windows the rendering is faster, and other people saying that with them is the opposite, with some minor variations like people saying that linux is faster for plain downloads while windows is faster for web browsing due to better graphics.
(by the way; I haven't installed any graphic card driver on windows, which is still running on 1024x768, while linux runs on 1280x1024, with the "nv" generic driver, without fancy options, not supported by my old card) The closest to a suggestion of possible solutions was someone saying tha compilation may affect performance, I guess it was both about kernel compilation, and the web browsers themselves.I'll google a bit more about how to "compile for speed", both kernels and programs (maybe the x server

I have Etch running in my laptop. I found that if the laptop is only running on battery, the disk seems to performs slower than if I running on a power adapter. How do I possibly check the setting and fix it?
I'm the only user on the system most of the time and I keep it as minimal as possible so it's not other services and programs keeping the disk busy.

using mint 10, now after updates my system is barely working. The programs were no longer showing in the task bar, and the system was running much slower.
[code]...
This repeated over and over again. My temperature was never to high 40-55, and I found a suggestion to update my kernel to 2.6.37-020637. After doing so there is no longer the thermal limit exceeded error but the computer is still running poorly. The system is slow and again no programs are showing up in the task bar when open.

OpenSuse 11.2
LXDE (Latest version)
It used to have a lightening speed. But now every application is taking few seconds to start, even on Konsole, the commands take some seconds to get typed ! (I literally have to wait for cursor to move and commands to get typed on Konsole). Folders are taking some seconds to get opened !
I rebooted the computer but that proved to be useless.
Here the ps output:
Code:
anisha@linux-uitj:~> pstree -Apuh `id -anisha`
id: invalid option -- 'i'
Try `id --help' for more information.

I have EastLink cable Internet and I have the fastest residential service money can buy, I get speed test results of 30mbps down and 2mbps up, that being said, my Internet was lightning fast on windows and Mac but when I installed Ubuntu, which is my favourite OS, my Internet is very slow and laggy. Sometimes it could take several minutes for a web page to load and some torrents download at 1-2 MBps and some download at under 100kb/sec, some web pages load instantly, some take longer.
I've searched other forums I found was turning off IPv6, I am not really sure what that is but I followed the steps provided and shut it off but did not notice much of a difference. I am basically a beginner when it comes to Linux, I use the OS for my day to day school and entertainment. I listen to music, watch movies, do school work and such since I am a university student. I really love Ubuntu and don't want to be forced to go back to Win blows, I really don't like windows at all so I would really like to solve this issue and stick with this operating system.

I recently switched my mom from Windows to Fedora , and ever since her Internet speed went down. Now it takes, on average, 6-8 seconds longer for her to load a web page with Firefox. Tried to replace the modem -- didn't help. She is on a DSL connection.
But here is the striking part. Her BitTorrent speeds are better than mine, and I have a cable rather than DSL.
I can't for life imagine how these two can coexist. An innocent web page takes forever to load, and torrents are so fast. By the way, she does say that torrents used to be *even* faster on Windows.

Installed 11.04 on my Acer Aspire 5742-6674. It has a Atheros adapter. In my Windows 7 partition, its a AR5B95. But Ubuntu is says its a AR9287. I'm using the ath9k driver, version 2.6.38-8-generic-pae. I tried the following:
Code:
sudo -s
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf
reboot
Still not working right. My wifi works ok at first...gets slower and slower...and eventually times out on everything. At that point, I have to restart the computer so it can work normally for a short time. Works totally fine when wired. Works totally fine wired or wireless on my Windows 7 partition. Both wired and wireless worked fine when I was using 10.10.

"Dell 1525 WLAN PCIe card with11n mini-Card & external antenna" wireless card. It got recognized fine by FC12, but it was rather slow. I had read that life would be better in FC13 with the new kernel. After a long wait, I upgraded to FC13 yesterday.
It seems that the wireless is indeed faster. However, it it clearly a lot slower than under Windows 7 (it is a dual boot PC). My test is simply to play say Hulu in full screen: under Windows it looks fine, under FC13 it plays in slow motion.

I have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.

I've been using fedora on my Lenovo R61i since I got it...I believe the first version I used on this laptop was f10. I always try to keep it on the latest distro and I also enjoy a clean install every year or so. One thing I was always impressed with was how quickly I could go from sleep to back up and online. So I decided it was time for a clean install this weekend to fedora 15. Now when I wake it up (open the lid), it takes over a minute for the wifi to connect again. This hasn't been the case for the last 4 distro's so I'm wondering what I can do to speed that process back up, is there a particular package I can downgrade or is this something on their radar already and I should just wait for an upgrade?

Just installed the latest 11.04 64bit ubuntu, using std cd install alongside windows7, ticking the "add all extras" option, to ensure I got all the latest drivers etc.. The pc is brand new
Acer emachines E644 - AMD 2 Core C-50
3Gb DDR3 mem
500 Gb hard drive
Pre-installed: 64bit Win 7 home premium I've literally changed nothing in win7 other than using wubi to install ubuntu 1st time around (ubuntu appears as a win program - and was un-installed as such). Note: It is too late to now check, but......... under wubi/win7 I had no sense that the browser firefox was running slow - i didn't do a speedtest.net cos of other priorities (and it seemed fine). On advice, I started again (new partitions etc). The Problem: Ubuntu is now 25% slower (broadband) than Win7! Actually, it feels worse than that - more like it was on my previous lap top that had 512Mb ram running xp. Here are the results after switching os's a couple of times.
[Code]....
Firefox managed one spurious result of 5.89, but the graph (on the speedtest display) was absolutely all over the shop (like it's overall results). Compare that to iExplorer - total stability, and in fact, more like 30% faster + a much better ping. Anyway, I guess you know all this, I've seen that plenty of others have noticed this speed drop in the past, so:

I used www.speedtest.net to test my download through firefox first on vista and then on Ubuntu (9.04) - it is a dual boot machine.
Whilst I get between 18 and 19 mbs on Vista I only get 4.5 on Ubuntu - how do I fix this - is it an issue with my ethernet drivers or my setup?
I am on a 20mbs cable modem - I connect via an ethernet cable to a router - which obviously connects to the cable modem.

I have a desktop running Ubuntu 8.04. I installed 10.04 on my laptop. When I mount my desktop music folder on my laptop and transfer files, they now only go at 100-200 KB/s. When I had 9.10 installed, they transferred at 1-2 MB/s.
This is the command I use to mount the directory:
sshfs matt@169.254.6.233:/home/matt/Music/ /home/matt/Music/desktop/
Is there any way I can speed it up to get it back to max speed?

My school has (once again) chosen to change their wireless network. This means it has gotten a lot slower, and that only our hotspot works. Our hotspot however is secured so that im unable to enter facebook, and a lot of other websites, etc. So what i did in windows was installing a program called hotspot shield, which redirects you ip through a server, so the LAN Admin basically have no control of what you're doing if he haven't got more skill than the one we have. I think what Hotspot shield does is making a vpn connection (correct me if im wrong) and i would certainly like to do that i ubuntu as well.

Hi. I have Ubuntu 10.04, nm-applet is running in the background, my battery icon and sound icon are showing but my network icon has been missing for the past 2 days. It was working fine before but now it's not. How can I fix this issue if I don't have an ethernet cord? Is there a way to roll back the recent updates or do I need to reinstall my network manager?
I've tried restarting the system and I've tried killing nm-applet and reloading it using Alt F2. I get some Debug error.
When I try to run nm-applet --sm-disable
It says an instance is already running and then gives me a warning.
I tried removing "iface eth0 inet dhcp" from /etc/network/interfaces and then tried restarting by "sudo /etc/initi.d/networking restart"
It says:
What can I do to connect to the internet? I have a flash stick if its possible to download a .deb package on this mac and transfer it over to my other laptop to fix the problem. If its possible.

I have been running opensuse 11.2 successfully on my IBM NetVista 1.8 GHz for a year or more. Response is quick, no problems.
Downloaded the DVD for 11.3 and installed it (new install replacing the / system partition but leaving /home intact, renamed /home...kde4 to .kde4old). Install was fine, but on final boot the response of 11.3 was noticeably slower than 11.2, I would estimate about half speed. I tried compiling a new kernel to see if it improved, but the kernel compile was taking for ever so I stopped it. Editing the kickoff menu was close to impossible - saving a change resulted in "Updating system configuration" which would crawl to 100% and then start over again; after the 5th iteration I cancelled it.
In fact this got so bad (slowness, odd errors) that I am in the process of restoring 11.2. This new install of 11.2 is noticeably faster again than the 11.3.
My system has a good hard drive and 1GB memory. Am I underpowered for something in 11.3? I could not figure that there was anything specifically different in 11.3 that could be disabled to restore the speed of 11.2.

I've been using 11.04 64bit for a few days now and overall it's very nice. Only thing I've noticed is the boot up time is slower than 10.04.
Is there a way to speed it up?
I'm running an Acer Extensa 4420 laptop.

I have a dual boot machine with Fedora 12 and XP SP2.
Recently I tested download performance using www.speedtest.net. Using seamonkey on XP, i got 22 Mbps on my Comcast ISP. Not bad! However I then tried the same test on Fedora 12 with F12 seamonkey and got 16 Mbps. Thinking it must just be seamonkey, I tried the F12 Firefox and got 12 Mbps
This seems like a pretty big difference. I checked around on google and found several threads decying slower mozilla performance on Linux. I tried the suggestions to turn off ipv6 support, but there was not much improvement.

Is there way to tweak it in some way so the speed is back, because before F13 World of Goo played perfectly and now in F13 it is playable but not "fluid" as before? Also if it is because of changes in F13 considering graphics what to expect in future, would performance be back?

Since I use my computer for some intense processor calculations, without any fancy graphical needs, I decided to apply a mild OC on the BIOS settings, to speed thing a bit up.I own an AMD Phenom II 1055T (2.8GHz) cpu. I changed the base freq from 200 to 203, and changed the multipliers of the standard and boost freqs to x15 and x16.5, so now the BIOS reads 3045 MHz and 3349 MHz for both speeds.
