Ubuntu Networking :: Slow Browsing - Fast Download ?
Feb 12, 2010
I'm using wlan and I'm behind a NAT firewall. Downloading with BitTorrent can reach speeds of 1,5MB/s, but browsing is incredibly slow. Chromium/Firefox seems to hang forever on "connecting.." or "waiting for". Sometimes pressing the reload button will speed it up. I have two Ubuntu boxes and they are the same way.
I don't get it, if downloading is so fast, how can browsing be so slow. Yes I have disabled ipv6 in grub and in Firefox, don't know how to do it in Chromium. Have 64-bit Ubuntu. Cnet wlan card using rt61pci module.
My wireless seems to be fast for a good 30secs then bang takes good while to load the next page almost as if it's disconnecting and then reconnecting/scanning reconnecting. Why cant it stay connected. I have WAP PSK security here is my network setting please let me know if I should change any of them:(side not is there a way to fix this problem occuring so frequently it says on the wiki that it should only occur once in a whilce https:[url].....
I'm running 11.2 on a Dell Latitude D630. Everything has been great other than issues with Suspend and hibernate not working correctly. However after about a month of use browsing the web has really slowed down bad. It doesn't seem to matter if it's in Firefox or Chrome either. I am using a wireless connection that is getting the signal at 85-95%. Even though I still tried using a direct cat-5 connection to the router and it was still slow as well. I have the fastest broadband connection my cable offers and my windows boxes on the same network are still flying.
Browsing via SSH Tunnel very slow When browsing in firefox at work via proxy through ssh on my 8.04 server the speed is near dial up. I have compression enabled, tried restarting ssh, and rebooting the server but it remains so sluggish. At home the connection is quick but the speed is lost in translation once I ssh in. I also tried adding "UseDNS no" to the ssh config but that did not help with the slow login or any other speed issues.
my computer is very slow to view regular web pages, and generally fails to load them. It seems to be a problem specifically with webpages - I can work over SSH, use email, transfer files over FTP connections, with no noticeable problems, but any regular website (including this one) can take an age to load. This happens regardless of the browser I use (at least, it happens on Firefox, Opera, and Chromium), and regardless of wired or wireless connection (though admittedly I've not tried using a wired connection very much). As far as I can tell, it can also happen on any website. It is specific to linux - my computer is dual-boot ubuntu 10.04/Windows XP, and there is no networking problem when I use Windows.
I don't know if others are experiencing this but browsing is extremely slow in firefox after "upgrading" to ubuntu 11.04. I have not tried other browsers. Even checking for updates fails several times.
I had to re-boot to windows to post this thread and now it's working fine. It's been 3 days since upgrading and I've observed many times that there's no such problem in windows while I have to wait like 4-5 minutes and refresh many times to open a single page. Some sites like google are quicker though. I use firefox 4.0 both in ubuntu and windows. I didn't have this problem in 10.10 and it took me about 5 hrs. to download 1 GB upgrade packages.
I'm running Mac OS on a home network that includes a Win 7 machine and a Ubuntu box (Ubuntu 11.04 (GNU/Linux 2.6.38-8-generic i686)). Connecting to, and browsing the shared drives I have on the Ubuntu box (which acts as my server) is extremely slow from the Mac, it seems that the icons especially take ages to load. I've found a few suggestions on the net that I've implemented to no avail i.e. socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 Are there any other settings I should play with, or is there an alternative to samba that will work faster on a mixed network and be compatible with everything?
I have a strange problem that I cannot diagnose -- slow wifi. About two or three weeks ago, I noticed that my wifi began to slow down dramatically. The problem is the same on my ubuntu laptop and my ipad. But when I connect directly to the router with a network cable, my connection is fine. So it is definitely a problem with the wifi signal itself.
What I have done so far: (1) I checked all of the MAC addresses connected to my wifi. I identified my tivo box, laptop, and ipad. Nothing else.
(2) I used [I]wifi analyzer[I] on my android phone and selected an unused wifi channel (channel 8).
(3) I changed the username/password on my wifi signal. I also changed the password for my router's admin privileges.
(4) I restarted my router and computer. None of this helped.
It can be summed up by saying the internet works fine some moments then becomes so laggy a few minutes later it is completely unusable. This is what has happened so far. First I went to scottrade trading platform, it takes real-time quotes of stocks and graphs them, allows you to see account information. It was working amazing for about 20 seconds, then out of nowhere the internet just stops working on it completely and wont come back. Then I tried WCIII. The patch would not download at all. I couldn't even manually get it. Then 3 minutes later I try it again and it starts making progress.
Ubuntu update files are downloading the slowest I have ever seen before. I went to ....., the videos download really fast for a few seconds then they just stop. No progress at all for at least a minute or so and then they crawl back to making progress. Web pages I visit work fine one moment, I go back to the exact same page a minute later and it doesnt work at all, takes a few minutes just to load.
I'm having an issue where a server in CA (1000/full) and in VA (100/full) have very lopsided data transfer.
CA -> VA with iperf shows ~20Mbps VA -> CA with iperf shows ~93Mbps
If we change the CA server to 100/FULL, transfer speed is 93Mbps both ways.
Some tuning was done to TCP window scaling parameters, but it won't correct the issue, just improve the CA -> VA numbers to what is listed above. I will say, turning TCP window scaling OFF will lower the transfer speed both ways to < 20Mbps.
The only clue I have when looking at wireshark dumps is that the window scale going OUT would never go past 10240 (scale is 8, so 2^8 x 40bytes). In the opposite direction, the window size will go above 3MB (scaled).
It is not a bandwidth problem as iperf with UDP shows 93Mbps both ways. Local transfers (CA 1000/full to CA 100/full) show full speed both ways, so I feel it is strictly related to TCP window scaling.
RedHat 5 64-bit on both sides. Any ideas why it won't scale above 10240?
This something I have only experienced since the final install.I'm using a fresh firefox profile with NO extensions currently. The only change I have made is to disable ipv6 to see if it helped with the following problem. Browsing web pages is stupidly slow and much slower than I am used to.Downloading in firefox is normal and running at speeds I would expect.For example, I have downloaded several distro .iso's over the past two days and they have been consistently downloading at 1MB/s +This is only affecting browsing web pages and it's affecting all of them, even the basic google search page takes at least twice as long as normal.
web browsing is going SUPER slow in my samsung N150 netbook with dual boot(win7/ubuntu10.04). Windows counterpart working flawlessly.
Into the details:
The problem is, i go into a website and it seems to renderize by chunks, ie i enter my favorite PC hardware forum and it is like this when loading: Processors...1sec....Vid cards....1sec...Memory...and on and on until the bottom of the page is reached. The normal behavior is: Click...forum loaded ,as on windows.
By default i use my wireless conection, but also tried wired one to no avail. Also tried it from the live cd and i have the same problem. Some sitess like google, gmail and ..... load normally(instantly). I've tried disabling ipv6 as adviced in several parts and had no results. I used the default firefox 3.6.6, firefox 3.6.7 and chrome with the same results.
This is the info for my wireless adapter just in case:
I have looked at other threads on this subject and am still confused. Several weeks ago I had issues with browsing taking forever to resolve a page. When I changed my router to Open DNS settings that seemed to fix the slows and when I replaced the Open DNS IP's with the Google IP's, things were even quicker. Now I am back to the slows but there is no resolution latency it's just a delay when clicking a link, nothing happens and then the page eventually loads but you see the ads write on the page after the text loads. It's just not snappy. My nsswitch.config looks like this:
# /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality.
I'm having a major dilemma here. Up until about a week ago, my download speed was at a rather nice 160-180KB/s, and I was rather happy with that. But, it slowed down. A lot. now my max d/l speed is about 40KB/s. I download stuff a lot, so having this slow of a connection is torture for me. Oh, and on internetfrog.com on the speed test, it says my d/l speed is supposed to be about 321KB/s and for some reason it can't even detect my upload speed. Strange. Any ideas about it?
Like the title, that is my problem. I'm using cable modem with 3mbps. It is Linksys Docsis, wired networking. When I download a file using ubuntu 9.10, my latency time (ping time) sky rocketed to 2000ms average, while in XP none of this happens; I tried to download the same file from the same website. In ubuntu 9.10 my network setup will be, well... nothing. I'm using DHCP automatic detection. Same thing in XP.
I don't want to go back and forward using XP for the internet. Funny thing though, none of this happens while I first started ubuntu 9.10. I didn't configure anything with networking. It is the way it is from the beginning. The only thing I tried was ubuntuone. But that like months ago, and the problem I have with slow internet connection only appear this March.
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.
So i am very new to linux based OS. Just started getting used to the terminal. but my problem is i am trying to install a game on steam and it is downloading very slow. i am used to getting close to 700 kb/s on windows 7 but on ubuntu 11.04 i am only getting 170-180 max. now i have searched all over and tried to fix it on my own but i just cant figure it out and am getting very frustrated. so if anybody has an idea as to how to fix this it would be greatly appreciated. (have looked through the forum by the way but as i said im new to linux and im not actually sure if im looking at the right things) but im using a wired connection. it says im connected to something called auto etho. and there is something called a loopback connection or something like that.
I have two Ubuntus installed. A 10.04 and a 9.04. In 9.04 if I watch a video in Firefox, it works very smoothly and nicely. Using the "top" command, totem-plugin-vi is using the most cpu time at about 16%, and xorg is using about 5%. But in 10.04, totem is using 72% and xorg is using 26%, and it looks really choppy. I think watching DVDs is the same way. I checked "Hardware Drivers" in the System->Administration menu (in 10.04) and it said "No proprietary drivers are in use on this system." I'm guessing maybe I'm using different video drivers on each system, but I don't even know how to check. and here is an excerpt from lspci:
The local files copy speed from one disk to another is satisfyingly 60+MB/s, but this cause problem to other application, windows gray out, firefox freez, basically i have to wait for the copy to end to return to the computer.
On my computer, I'm using 11.3, KDE 4.4.4 and Firefox 3.6.8. Firefox is so s...l...o...w..... It's slow loading and it's slow browsing. Konqueror takes 1, maybe 2 seconds to load, and another second to load the home page. Firefox takes a good 30 seconds to load. The only message I get when loading from a terminal is about not using a shared database. I don't hear the disk churning like it would with a fragmented disk.
I can't believe everyone is having this response, the hue and cry would be enormous! Anything to try? Should I try loading another browser? I tried Opera on 11.2 and didn't really like it, had problems with a lot of content. What about Sea Monkey (Gad, I HATE words with monkey in them!) Konqueror won't show a lot of videos and I have problems using the back and forward buttons. I'll wait for fixes but in the meantime.
I'm not sure why, but over the last couple of days when I browse the web with my Centos 5.3 machine running firefox 3.0.5, it takes a very long time to load web pages. Loading the app itself is pretty quick, and I have not issues with system resources (it's an HP Proliant ML115 server, with dual opteron processors & 3Gb RAM). Looking at CPU & disk useage there's nothing out of the ordinary:
I have in my pc (ubuntu 10.10 32 bit) a folder with about 10.000 files. It is a samba shared folder and so far I could browse fast and easily those files in another old ( Pentium4 1,5Ghz) PC with WinXP. I installed ubuntu 10.10 but the browsing now is toooooooo slow , although the old Pc's performance is considerably faster than before (when I had WinXP). Also, although the old PC's speed is satisfatory now, would it become even faster if I installed an older ubuntu distro?
I have a fast server running Debian 5 (I tried to upgrade and everything broke.
So I'll stay with Lenny): Core 2 Duo 4Gb RAM RAID 0 100mbit
When I use the -X command and try and run applications to my desktop, it is VERY slow. Firefox takes 20 seconds+ just for a right-click menu to appear. It is completely unusable because of this speed. And this is after a clean install of Debian 5.
I've tried on multiple clients (Windows and OS X) and it is always slow! Even though both computers and connections are fast. My home connection is 100mbit too....
So the problem is not bandwidth or resources, the problem must be with the server/software? Any ideas why tunneling X11 applications are so slow? Is there an alternative X11 software I could use on the server?
1 thread in FTP to this server gives 10MB/s (100mbit). So X11 should be fast? And btw, I'm tunneling through SSH.
I have a fileserver running 10.04 server 64bit and samba. I connect it to my desktop which is 10.04 desktop 64bit.I have the server mounted on my desktop in fstab as://10.0.0.2/share /media/share cifs guest, uid= 1000.Up until 30 June 2010 it was all fine. Now when I write the server it is very slow e.g. 2Mbps though when I read I get >100Mbps so I think my network is still ok. If i use nautilus smb://10.0.0.2/share I can write at >100Mbps and also read at >100Mbps...So any ideas why the write speed via the fstab mount samba has started to go really slowly in the last couple of days?
I have a 2.6 P4 with HT and 1GB of PC3200. i'm using an RaLink 2760 based wifi card. i compiled the driver from source, don't think it matters because i get this problem on ethernet as well. video is RV280 (radeon 9200). i have 3D accelleration supposively and get 570fps steady with glxgears. i'm in F11 updated as far as yum will take me.
When browsing websites, usually forums but even things like ....., the computer acts like it's being bogged down by something. i scroll down a page and it takes a few seconds for the screen to catch up. i understand i'm not running the most up to date hardware but i don't think this machine should have any problems with web browsing.
I have a connection an its slow in both ff and chrome...however i can ping sites and get the same response time as my xp machine which runs fast. usually around the 40ms mark with no lost packets.
Also when i do installs eg. of chrome etc, i was getting up to 500kB/s download. I just cant seem to replicate this browsing, its loading up at a dial up pace. The last time I had an issue like this was setting up my mums work laptop on our home network where the work had specific proxy settings, so we turn the off and it works fine.
I do not know how to tinker this

I've recently installed openSUSE 11.4 (64 bit) on my system and am experiencing severe performance issues with websites using https (any site using https). Page loads over https take anywhere between 30 seconds to 2 minutes. It's the same issue posted here Secure sites load slow or not at all -- there was no confirmed solution.
- My router/hardware configuration has not changed in a long time and I've run Ubuntu, Arch Linux, and Windows XP on the same machine within the last year and have not had any issues. - I also have a laptop running Arch Linux (kernel 2.6.38) and this problem does not occur using Firefox 4 or Chrome. To add to the madness this problem occurs while running Firefox 4 inside a Windows 7 guest via virtual box, but NOT while running IE 8 inside the same guest. - This issue occurs using Firefox 4, Chromium, Opera, Konqueror, and Arora. - I've disabled ipv6 in Firefox via about:config. - I've disabled ipv6 in yast and have attempted to use both the "ifup" and "networkmanager" options. - I am not using a proxy server. - I've attempted the fix posted in the Ubuntu forums for a similar problem [ubuntu] [SOLVED] Banking Site is very slow.
I'm running Ubuntu 10.10 on my Precario Laptop I'm connected via WiFi to an Edimax BR6424-N and i cannot login to Msn and browsing is extremly slow as soon as i connect to any other network but myin everythings fine, Ive searched the web alot and found that i should down the mtu in linux so i did, from auto to 1350 and still i keep getting disconencted from msn and briwsing is just extremly slow, Im In the same room as the router so distance is not the issue...
I have installed Wubi (Ubuntu 10.10) recently. It takes more time to boot than Windows. But my main concern is that my browsing speed is much slower compared to that on Windows 7. How can this be resolved?
