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.
When I copy files to my External NTFS HDD using Ubuntu the write speeds are about 10-12 MB/sec, but when I copy files using Windows the write speeds are about 25-30 MB/sec.
Exact same files, tried all three ports on my netbook and even timed it to see if the speeds are by any chance miscalculated by either operating system and Ubuntu is definitely writing at half the speed.
So what could be the problem? When I had Windows on this Netbook I never got had a problem with write speeds so I don't think it is a hardware issue.
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.

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.
Has anyone else noticed that file transfers on Maverick are significantly slower than on Lucid? A review of Maverick on Tom's Hardware finds that it is considerably slower. My own test says: On 10.10, file copy between two NTFS drives maxes at 30 MBytes/s; on 10.04.1, the same operations clock in at 40 MBytes/s. Both drives are capable of rw speeds of 70-90 MBytes/s, which I got on WinXP, and hdparm's cached read results back that up. Any ideas why file transfers are so slow, and especially why Maverick is even slower than Lucid?

Despite this I am experiencing a serious problem which may cause me to revert back to Windows 7.I have a USB 3G modem: ZTE MF622 on the KKTCELL network.I have got this modem to work with wvdial and Gnome PPP, however i cannot get speeds over 60kb, Windows gives me well over 200kb.
I have tried a number of things but nothing has worked, it seems that no-one has posted a solution to this annoying conundrum.
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'm moving to Vietnam soon and was wondering if anyone knows of the best native linux way to circumvent the internet censorship there without slowing it down too significantly. I used to use proxy servers to access Wikipedia in China, but they were slow and unreliable. Not to mention, it was a pain to enable/disable it.

I'm using a Netgear WN11v2 wireless USB card, which I've read some people can't even get working with the default Ubuntu wireless driver. It works for me, but it disconnects fairly often, and download speeds are extremely slow, like 12-15 kB/s. I have broadband, and am running Ubuntu 11.04.

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.
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.

I am running Ubuntu 9.10 on a Dell inspiron 1520 with intel 3945abg wireless card. I am fairly new to linux and just installed it earlier in the day. Everything so far has been easy to setup and get running as well as the networking or so i though...
I can connect to my network and browse we pages just fine. However, when I download a file the speed starts high, drops down to around 50kbps and then works its way back up to around 1.3 mbps before dropping right back down. I tested a file on megaupload and it seems to bounce between 50kbps and 1.5mbps nonstop.
The driver i believe is the iwl3945 if that is the default driver. I have tried disabling ipv6 and that didnt seem to change anything. I've looked around on google and the forums and havent been able to find anything on how to fix this.
I am currently staying on a university campus in Taiwan. Internet on Ubuntu Lucid 64bit here is often painfully slow, except for connections to Taiwanese websites. I dual boot with Windows 7, and there is no problem there. For instance, I downloaded the same piece of software (Spideroak) on both Win and Ubuntu, with Ubuntu I had to try repeatedly as the download would not complete, and in the end it took several hours to download. On W7, it took 10 minutes. What is Windows and Ubuntu doing differently?
I tried disabling ipv6 for this session by running sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1, as a number of posts mention improving connection speed that way, but no effect.
I know that websites from Taiwan are working well, because I am getting my Ubuntu updates from a Taiwanese mirror: updates are fast, except for packages in the 'partner' repos (presumably not loaded from the mirror) which take hours to load, if at all. I don't want to depend on Windows for large downloads... (I don't want to depend on Windows for anything).
I'm on Ubuntu 10.04 and I'm having problems with internet speeds on wifi. I have tried the two available networks on my university campus and both of them are very slow with 10.04. I'm not having problems with Windows 7 running on these networks. Although, the wired network works perfectly fine, with normal speeds. I've looked around for help but I could not find anything specific to this problem.
View 2 Replies View RelatedI've just managed to access my windows share from Ubuntu but am now getting write speeds (to xp share) of only 9MB/s over my wired network, anyone have any ideas as to why this may be? I've googled but can find no specific answer.
My NIC is:
Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
(from lspci) on a Dell studio 1737)
I'm wondering if there is anything I can do to get the best speeds possible. I pay for 16mb/s connection (with charter) and I was getting about 4mb/s. After upgrading firmware, and changing some encryption settings on my router, that went up to about 6mb/s. It's improvement, and I'm happy with that, but I'm looking for that 10 more mb/s
So, is there anything in Ubuntu to tweak to optimize connection speeds? Also, if it affects anything, I'm using a linksys WRT320N router. I was going to use the 5.0ghz band, but my wireless adapter is an 802.11gb, so I'm stuck with 2.4.
First of all I have two Gentoo Linux computers. These computer both have Ethernet ports that support 1000MB/s speeds. Here is the ethtool report for both of the cards.

My question is why is this so slow and how do I get my speeds closer to 1000Mb/s?
I have had a fairly perplexing problem with my Lubuntu Maverick installation on my laptop for the past few weeks. My laptop is connected to a DSL-based LAN via 100mbps Ethernet - pretty typical. Usually, the download speed from most websites tends to be around 340-350kb/s. However, its Ethernet connection seems to be having some strange hiccups. The speed starts out at normal ranges, but after about 5-10 minutes of internet use through any means (be it loading normal web pages, streaming video, downloading a file via a browser, or even other uses such as downloading a torrent using Transmission, or even a command line application such as apt, aptitude or wget, etc), the speed suddenly drops to around 40kb/s and will not raise again.
Once this happens, the drop is seen across the board. Again, once it happens, the speed of everything that accesses the internet is affected. Web pages load slowly, all downloads will only operate at a maximum of 40kb/s, whether it is from any browser, or wget in a terminal. The speed stayed slow until I restarted, which would give me another 5-10 minutes. My troubleshooting attempts yielded some very strange results, which I will relate here:.......
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

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 want to install Ubuntu but not as Dual-Boot (Other OS is Windows XP x64 edition).
Does Wubi perform significantly better than an Ubuntu version installed on VMWare or VirtualBox?
My computer has:Intel Core2 Quad Q8200 @ 2.33GHz. 4GB RAM. An almost empty 450GB HD (defragmented)
My wireless network is giving me a fit. Slow transfer speeds and then I lose connection and have to reboot.

I've been using Ubuntu for a while (though I would not consider myself an "expert") and have just gone back to school. I live on campus and connect to the network through an ethernet cord. On Windows, the download speed is 1 Mb/s by default, but if you go through and configure the network card (turning off the auto-negotiation and setting the speed to 10, duplex full) the download speed will increase to 10 Mb/s, a considerable difference. So, I tried to do this in Ubuntu by opening the terminal and typing the following:
sudo ethtool -s eth0 autoneg off speed 10 duplex full and all of a sudden, my computer isn't connecting to the internet. When I type: sudo ethtool -s eth0 autoneg on it suddenly starts working again.
I've recently purchased a TP-WNL951N PCI Card for wireless N stuff. I have a Netgear WNDR3700 for use with my AP and I've confirmed that within windows XP I can connect at 300mb/s.
Within Ubuntu though, it only goes up to 54mb/s. Is there something special I need to do to enable wireless N speeds?
Here's some info that I should probably put in:
Code:

I have installed libapache2-mod-bw and it works great to throttle download speeds to the clients (i.e. - the bandwidth out of the server can be controlled just peachy).However, I need to limit the bandwidth *into* the server from specific networks because my WAN links are tiny and do not have QoS or shaping of any sort (I know, I know - contracts in place - will be fixed in November - not my design).I know that there are ways to throttle this at the interface level (e.g. - wondershaper) but I'd like to allow full bandwidth to the clients that are connected locally. The server in question is for web file transfers (under apache2 on 443) and expected file sizes are up to 2GB so a per-network limit would prove helpful.

Looking into the trouble of slow windows resizing I ended up with the observation that for 1280x1024 it's reasonably fast while at 1024x768 it's extremely fast. But 1600x1200 is my LCD's native resolution.
At 1600x1200 my computer is quite slowly responding, resizing windows or moving columns width makes it stumbling, you can see the action clearly does not go right with mouse, it's always late. KDE 4.x is way slower than Gnome.

Glxgears gives ~4000fps with windowed mode and ~400fps at 1600x1200 maximized window. What is extremely amazing for me is that windowed mode takes 100% processor usage while 1600x200 maximized window (with window decorations) takes 30% of it, don't understand it.
Windows XP seems not to take care about 1600x1200 resolution, it's really fast.
