Several days ago responses to many, but not all, of my internet requests slowed from long to never.I'm on Verizon FIOS; running Firefox on a Debian Lenny system with 6GB or RAM and 500GB HD with 32GB cache.
internettrafficreport.com shows index of 84 for North America. I've pinged a few sites -- see returns from 16ms to 91ms.I've also rebooted my Verizon DSL router.
I have a pretty quick machine, quad core 2.66GHz duo processor, nice ASUS motherboard, high speed memory bus and so on. Basically, this is not a machine that's getting "maxed out" by playing some music.Load averages for the 4 processors according to htop are 1.48, 1.25, 0.85. Looking at the System Monitor CPU history I am seeing an average of perhaps 25% load.
However, when I am in a shell, I am getting a second or longer waits between key presses at times.My only guess as to why is that may be is that the streaming audio is on some very high priority so everything else gets put on the back burner. In any case, does anyone have any experience with this and a possible tweak that would give everything else a "fair go" so things didn't seem so unresponsive?
I have a home network consisting of 1 Linux box running Fedora 13, a laptop running Windows XP, and an HP Officejet Pro L7780. With the Fedora 13 box I have Firefox 3.6.4. I have noticed in the last couple of days a very sluggish response seemingly one site, amazon.com. I'll connect to the site but Firefox remains loading the page and parts of it will be missing. If I search for a particular item it takes forever to display parts of the newly requested page. I have hit stop and then refresh and sometimes the page will then come up although it's never 100%. Eventually I'll loose my router (which by the way is a Linksys BEFSR8.1 v3.01), in that if I ping it I'll get the error that it is unreachable. The laptop also looses access to the router. I'll then reset it (unplug/plug) and it'll come back up ok until I go back to Amazon and start searching again.
My question(s) are:
Can a router go bad and just show up bad with one site initially? In other words is the router slowly dying?Can a problem with a site affect the router this way?I have also changed my namserver settings in /etc/resolv.config and on the router with no real change in symptoms. It's always Amazon and I don't seem to have issues with any other sites that I visit. Any clues?
We have an environment where couple of webservers are being active behind the loadbalancer, the webpage is getting loaded extremely slow if we restart the apache on those boxes its responding very fine. So currently we are restarting the apache service daily basis, i have attached the config with this thread could anyone suggest how to fine tune apache so it works fine without restarting it daily?

I've tried disabling ip6, disabling avahi and adding options single-request to my /etc/resolv.conf - problem remains. If it helps when installing Squeeze was prompted to install firmware-realtek, which I didn't have. So downloaded onto usb from another machine installed once setup was complete.
I use Slackware 12.1 and I have a big problem that I can't solve by myself. I'm connecting to a LAN where there are almost 20 PC connected, all with static IP.
my ip: 192.168.1.205
netmask: 255.255.255.0
gateway: 192.168.1.1
DNS server: 80.58.61.250, 80.58.61.254
I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.
My problem is the following:

It takes a lot of time connecting to a internet web site! It's really strange because downloading a file the transferring rate is good, it takes some time starting, but it works normally. I wait almost 7 seconds after seeing a web site. All the others PC's (windows xp) can connect perfectly to network using static and DHCP. Trying with another wire in another room I've got the same result. My /etc/resolve.conf is configured with the IPs specified upper in this page.
I set up my linux router as a simple NAT router. I use CentOS 5.4. When I set up ISP proxy IP in the browser of client PC, Internet access is fast. When I remove ISP proxy IP from the browser, Internet access is slow.
ISP use transparent caching but I can use manual caching as well. Clients on my network with transparent caching get slow internet access and using ISP proxy get fast internet access.
ISP announce that we can use transparent caching or manual caching.
So, I set up my linux router with squid. I set up cache_peer TAG point to ISP's proxy IP. But the problem is the same. Using my squid proxy is slow and using ISP proxy directly is fast. All other network settings are correct.
How can I improve my internet connection using transparent caching. I don't want to set up proxy IP address on all clients.
I am having (seemingly) random trouble with my wired network ever since I installed Lucid. I have no problem getting an ip address from dhcp. However, randomly the computer will boot and although I have an ip address I do not receive any responses for pings on the network nor can I browse the web. If I sudo /etc/init.d/networking restart a few times (or reboot) it will start working. However, restarting the networking services (as mentioned above) again will cause me to no longer receive responses for pings or browse the web.
Furthermore, I have never been able to successfully ping if I manually set an ip address. I have un-installed network manager and I am using /etc/network/interfaces to configure the network. Using Lucid Lynx 64bit on a Dell Precision. I have pasted below the output of a few working commands. When I switch between static ip and dhcp I am commenting/uncommenting the lines shown in /etc/network/interfaces.

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'm finding that the internet speed in Ubuntu 10.04 is over twice as slow as the speeds that I am getting in Windows 7.I've tried disabling IPv6 through Grub and Firefox but it didn't really help much.. anything else I can try?Connecting through wireless at 54 Mbps.

View 9 Replies View RelatedI'm staying out at a friend's house in the middle of nowhere, and she's been complaining about how slow her satellite internet has been of late. So I decided I'd take a look. If I ping my server at home, I end up with these statistics:
Code:
// @ 1 ping probe per second
60 packets transmitted, 36 received, 40% packet loss, time 59172ms
rtt min/avg/max/mdev = 639.915/799.882/1209.119/104.763 ms, pipe 2
Compare that to driving 70 down the highway tethered to my cell phone: I see latencies in the 3000's and out-of-order packets, but practically none get dropped. If you ramp it up to 5 ping probes a second, the loss climbs to around 75%. To me, that seems quite excessive. The interesting thing is that all the packet loss seems to be occurring on download traffic - I set up tcpdump to monitor the packets on my server during the ping test, and all but 1 of the pings to got there, so the other 25 lost packets wondered astray on the return trip. I tested it with the client directly connected to the modem (it had the public IP).
So I'm quite certain that it's the satellite link itself that is the issue here. I've attached the complete logs from the ping test for your enjoyment. Of course, TCP corrects for the loss of packets, but with a latency of 800ms, resending packets takes a significant amount of time, not to mention services like DNS that just wait for a timeout to elapse (which is usually way too long). It can take 15 seconds to load a webpage. So I guess my question is, should it be this bad? I know satellite is generally terrible, but I didn't expect to see such rampant packet droppage.
I just installed dual boot Ubuntu 10.04 on my WinXP laptop. The laptop is a Compaq v2552us.
In windows mode, the internet works plenty fast.
In Ubuntu, I can't download a single update for hardware drivers or for ubuntu (it says there are 74 though).
It starts to DL, but max speed is about 800B/s, but that only last for a couple seconds before it switches to unknown. I am connected to my wireless router via cable, can't even get wireless to work (I suspect the aforementioned hardware drivers, which is why I need this to work).
I have 2 computers connected to my linksys router via ethernet cables.
My main computer is running Ubuntu while the other is Xubuntu.
When both comps are on, the internet works fine, but when my second computer is off, my main computer has super slow internet. Sometimes it takes 2 minutes and I get "This webpage is not available", and then I refresh that and it finally loads.
Why does it work when both comps are on? What could cause this?
I just installed and configured Slackware on an old computer I am using as a router.
The internet works fine on the slackware box (router) but all of the computers behind it are having issues. When browsing, some websites work perfectly fine, while others are slow to load, and a few don't load at all. I'm not really sure where to start on diagnosing this, so any help would be appreciated.
Also whenever I restart the computer, I have to use this command before the DHCP server will start. What do I have to do to get it to start up with the computer?
Code:
After installing Slackware 13 and configuring it as a router, I'm getting very slow internet speeds on my clients. It takes forever to connect to a website or downloading 100mb bin file also takes forever. On the Slackware box the speed is fine though. When I boot from my previous Slackware 12 drive, the speed on the clients is ok again.
I have compared config files from my old and new installation and haven't found a difference. from other posts I learnt that disabling IPv6 by adding it to the blacklist could help. But this didn't help me either. I have also compared a traceroute on both installations. This also doesn't show a (big) difference.
The only difference I have found is that in my Slackware 13 setup the following modules are loaded while with my old Slackware 12 lsmod is empty.
Code:
The only thing I can think of is a missing option in the kernel. I have used the huge-smp from the Slackware DVD, assuming this would have all the important stuff enabled by default. It this right?
Some additional info:
eth0: nVidia Corporation MCP51 Gb onboard Gb NIC, connected to LAN (static)
eth1: 3COM 3C2000 Gb NIC, connected to cable modem (dhcp)
dhcpd is running to configure clients in the network
arno-firewall installed
Files I have compared with my old (working) system:
Is karmic is slower for you all: if you're running windows ping a server on windows/ubuntu and compare. 9.10 is consistently slower for me. I've seen enough "slow internet" posts to suspect that someone screwed up bad. Everyone says it's ipv6, but none of the fixes work for me. Pretty sure it's ipv6 (or at least a dns-related problem):

I've been running Ubuntu 10.04 inside Windows 7 (demo version) for 2 weeks or so now and I really loved it. So much so that, last night I decided to burn the boot cd and put a full installation of it on the computer, instead of using Windows 7. After doing so, I started getting some small problems.
First problem was with aMSN, the webcam doesn't work anymore. It used to work when I was using the demo version of Ubuntu, but not anymore. I had to use meebo to get it to work, don't think that's a problem with Ubuntu though.
Secondly, Firefox is running really terribly. Whenever I try to watch a video, it stutters REALLY bad, as if it's maxing out my CPU.
Third, I'm getting an error message whenever I start Google Chrome, it says:
"Your profile could not be opened correctly. Some features may be unavailable. Please check that profile exists and you have permission to read and write its contents."
It plays videos well but half time the audio doesn't work and I have to restart Chrome. (I tried uninstalling and reinstalling through synaptic, but that didn't work, the problem was still there).
Fourth and finally, the internet is just really really slow. Since the moment I installed the full version of Ubuntu it's be REALLY slow. I tried a download through bittorrent and the speeds were terrible, I ran a speed test while downloading (upload was limited to 5 kb/s) and I was still getting speeds of just around 10kb/s. So I closed bittorrent ran a speed test again and I had 1mb download and .75mb upload with 31 ping. I ran the test again and got 42 ping with same download and same upload. While I was downloading, the ping was 309. My normal speed is supposed to be 6mb download and 1mb upload
I guess version 7.0X had internet issues aswell because, when I did a google search for a solution, it turned up several results on how to fix it for 7.0X, which didn't work because the alias list didn't have anything in there. (the fix had something to do with ipv6). I tried direct connecting my internet and the speedtest results were normal, so I've concluded that it has something to do with my router. However, I don't know how to do a firmware update or troubleshoot the issue on Ubuntu. I finally decided to give up on Ubuntu and switch back to Windows 7. However, my drive is currently formatted into ext4 and I need to go back to NTFS, how do I do that? Could I just use gparted?
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.

I've tried wireless and wired connections and they either dont work or will load half a web page after a few minutes.

I have just built a PC based around an i7-860 and Asus P7P55D mobo. It was running fine until the big update that happened today and now the internet is like treacle. I did the same update to my other (different hardware) PC and all is fine with it.
When I load the earlier 2.6.32-21 kernel instead of 2.6.32-24, the new system works as it should and the Internet is very fast. This suggests to me that the kernel update is the problem, most likely the NIC driver. This motherboard has a Realtek 8112L NIC fitted.
Has anyone else had this issue and what is the best way around it other than loading the older kernel and hoping that the next update will fix it?
Previously had 2 Ubuntu computers setup Computer A (192.168.1.101) <=> Computer B (192.168.1.100) -> Internet Computer B was the gateway, and it is dual boot, one drive Ubuntu, one drive XP. I'm using XP as the gateway now, but Computer A is extremely slow, virtually nothing getting through.
Have checked sysytem logs, verified /etc/hosts file, and all the network side of things. Can ping either IP adddresses from either computer. On the XP side, have modified hosts and lmhosts, and the XP computer has very fast internet connection.
Did have Commodo firewall running on the XP, disabled that, and checked that no Windooze firewall was running. Have restarted the network on both computers a number of times. Can't figure out what the problem is. It's obviously on the XP side, as when I booted to Ubuntu (previously) on Computer B, the gateway worked just fine. Have checked the whole tcp/ip side of things on XP; seems to be okay.
I have Ubuntu running on my HTPC and for the longest time all this was working fine. Now all of the sudden my Internet connection is all sorts of slow. Chrome browser, transmission bt, apt-get, all have the same speed issue. I tried disabling IPv6, changing my DNS and installing all the latest updates. Nothing works.

After searching the internet for a while I came across several article saying to disable ipv6, which I have done, but the issue persists
View 2 Replies View RelatedI have an old HP pavilion laptop (2005) that was useless.I installed Ubuntu 10.10 on it and it became a working computer again. It was excellent, snappy, it was as if I had bought a lower end modern laptop.Internet was working great.I did not have any complaints (in fact, I thought that a modern computer running Ubuntu would beat my so adored macbook, speed wise). For some time I had 2 efficient computer, a macbook and the hp with the Ubuntu OS. So on the last weekend of February, my internet got extremely slow on both computers. After that annoying weekend (February 28) the internet on my mac was good again,however, the internet on my linux continued to be messed up.I tried disabling IPv6 on my machine and on firefox, tried the openDNS, the MTU stuff, but nothing.I even formatted my disk and installed ubuntu again (all this using the installation CD).However, apparently the installation CD uses some of your existing configurations (for example, the layout of the close, minimize,maximize:menu buttons on the corner of windows did not go back to default). So I'm guessing whatever was messed up with the computer didn't change back to default or the previous configuration when I first installed ubuntu. To give you an idea of how slow the internet is, installing alien (terminal installation),I got low speeds of around 150B/s (no typo here, it was bites, not kilo bites) and the fastest around 5,000B/s. The fastest I got was downloading chrome at 6kB/s but that didn't last even a minute. So given that these transfer rates are obtained both on firefox and the terminal, I'm assuming it is not a browsing problem.
A thick headed solution, would probably be to install windows again to get the network configuration to "standard" and then install Ubuntu formatting the disk again (using the CD).I'm using ethernet,so,thinking it might be cable problems, I did try to use the cable that was on my mac on the machine with linux. No success there.
Problem with Jaunty (yes I know its old) on line. The thing is some web pages are fine and some just never seem to open up with Firefox.
I dont seem to have any problems when I attempt to ping for instance google.
ping -c 1 google.com
PING google.com (209.85.149.103) 56(84) bytes of data.
64 bytes from ber01s02-in-f103.1e100.net (209.85.149.103): icmp_seq=1 ttl=59
[Code]...
I also can open up for example, The Guardian (newspaper) home page, but when I try to open any page within the site it will try loading to no avail.
In general it seems to be almost 50% open and 50% will never open.
Network Connection type DSL
MAC address is blank
MTU automatic
IPv4 automatic (PPPoE)
