Ubuntu Servers :: Slow After Upgrade To 10.04.1 LTS
Dec 31, 2010
About 3 months ago I upgraded from 8.04 to 10.04 and the experience has since been very problematic in regards to overall performance. The problem is mostly with MySQL, but I have also noticed that the smallest amount of disk IO slows down the system a lot. I was expecting a slight performance improvement before I upgraded, but instead I got a very big opposite. I tried tweaking the MySQL server settings, but the improvement has been minimal.
At this point I am going to have to make a new system with something like Centos (I've heard good things about it's performance). Before I do, I want to give Ubuntu one last chance and ask if anyone knows anything that can be done to fix the performance issues. At the very least go back to something that is comparable to 8.04?
I have a virtual machine that was running Ubuntu Server 9.10 under Hyper-V on Windows Server 2008 R2 and the performace was acceptable. I run it in text mode with no X windows. I use it for LAMP. I upgraded to 10.04 and now the console is almost unusable it is sooo slow. It starts booting and text is painting fast and then something happens to the video. The screen goes to green, draws a few vertical lines, then clears back to a black screen but you can tell it is in a new video mode and the rest of the boot process and logging in and using the system is horrible because scrolling and redrawing of the screen crawls. Never had this problem in 9.10.
I'm sure that it is a "flipping from a text to a graphic text mode" issue at some point during the boot process. I've tried playing with kernel options (vga and nomodeset) but neither helps. When it gets about half way through the boot, something is making it change and then I'm screwed.Any ideas would be greatly appreciated. I enabled ssh and I can ssh in with no problem. Performance is great so it is definitely the console now being in a "graphics mode" kind of issue.
My 10.10 to 11.04 upgrade has been running now for 2 hours and says it has 15 hours left! Are the servers just max'ed out with people upgrading? We bit worried too after seeing posts that say that some Nvidia cards aren't working with 11.04 but I'll have to wait and see for mine. (Quadro FX 3800)
Since upgrading from Heron to Lynx (64 bit) Gnome is slow to start. It seems like it is waiting for some sort of automated timeout, since the harddrive stops in the middle of Gnome startup (after login) for around 10 secs or so. Is there a logfile of the startup-sequence somewhere that I could look at and/or post here?
I recently upgraded kubuntu from 10.04 to 10.10 Slower boot time First,systen will wait a few seconds on tty1 after a few seconds then jump to the login screen Then wait for a few seconds to type When I waiting the hard drive do not do anything My hardware is lenovo r400 Intel (R) Core (TM) 2 Duo CPU P8700@2.53GHz. RAM 4G Before the upgrade are quite fast boo Become like this after the upgrade
Since my upgrade to 11.04, ubuntu has been running real slow. When I click on the firefox icon on the side bar, it literally takes over 3 seconds to start opening up. And the same thing goes for folders. Is there something I need to tweak to fix this? And my computer is pretty fast on its own, vista runs very fast on it if that says something.
This is my first post here. Since upgrading to Squeeze from Lenny, I've noticed that authentication is quite a bit slower when running the command "su -" and sometimes "sudo" as well. Is anyone else having this issue?
I recently upgraded from 9.04 to 9.10, and Firefox is painfully slow to use. Changing between already loaded tabs takes almost a second. Scrolling through a loaded tab is also slow and jerky. Other programs (e.g. Thunderbird, or just browsing the filesystem) also seem slower when Firefox is running.
I'm running Firefox 3.5.6. My PC is Compaq Presario 2200 laptop (about four years old) with 768 MB RAM. As another data point, I also have the most recent version of Linux Mint installed on the same PC, running Firefox 3.5.3, with no problems. I've searched, and some problems have apparently been due to DNS problems, but I have problems when I'm offline (wifi physically removed), looking at webpages saved on my disk, which are already fully loaded, so it's not a DNS problem. I did try steps 1 - 7
I just recently upgraded my kubuntu install from karmic to lucid and now it takes about 10-15 minutes to boot. Directly after the upgrade it was pretty slow already, but it got worse every day from then. The karmic version was a wubi install I moved to a dedicated partition using lvpm. Here are the results from the bootinfoscript code...
I am getting a much slower boot with the 10.04 upgrade. After choosing which partition to use I get the blinking white cursor in the upper left hand corner and the "Boot from (hd0,4) ext 3..." sits there for a while before coming to the log in screen. There have been quite a few posts about this, a lot of people are saying disabling the floppy drive in the BIOS has worked for them. I don't have a floppy drive on my laptop.
I upgraded to ubuntu 10.04 lts yesterday. The upgrade went smoothly. but now I have a very slow internet connection. It is as if I am on a dial up when I have a broadband speed of 20 MB. What can I do to fix or perhaps roll-back the installation to the previous proper working state.
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?
After my upgrade the bootup seems to take a long time.I am dual booting with XP.From the boot menu when I select Ubuntu it takes 35 seconds before I get the login screen.Is this normal?Also, other apps seem to be running slow. Running Win 7 under VMWare Workstation 7.1.
Since upgrading my mythbuntu box from lucid to maverick my boot times have been much slower. Looking at dmesg I can see delays. Can anyone who knows more than me point me in the right direction to fix these?

im willing to upgrade to 10.04, but before i would like to have installed the regular upgrades. They make a total of 100megabytes, but my problem is that the download speed is soo slow, its like 2000 bits per second... amazing. I don't where the problem is. I have broadband, and internet works just great for the whole system and applications.
Sorry for my english in case you didn't understand something!
Is anyone else having issues with their mouse/keyboard responsiveness via Synergy after upgrading to 11.04?
If I plug mouse and keyboard directly into the desktop the issue goes away. But when I connect via QuickSynergy and share my mouse/keyboard the mouse is very slow and has low sensitivity.
Under Fedora 9 everything was fine. Now, when loading web sites, about half the time, there is a pause of several seconds before the page starts with a message in the status bar of "Looking up <domain name>". Seems like a problem with name resolution. Half the time, this isn't an issue ... wierd.
I've just upgraded from 11.1 to 11.2. My KDE apps (Firefox, Yast, Kmail) are now excruciatingly slow - particularly Kmail which is now virtually unusable. Before the upgrade on my 3GB RAM laptop the response was great - so something has broken during the upgrade process. What is interesting is when I open in Failsafe - the speed is fine.
My thoughts are maybe graphics card acceleration but why would it be ok in failsafe? Not really sure where to start looking here.
All of my PHP web pages are now loading incredibly slow. I created a simple "Hello World!" script and timed retrieving it from a terminal using wget and it took 3min 9seconds. A wget of the home page of a PHP-based site also took 3min 9seconds. I have a PHP script that I run from the command line that I use to look for malicious FTP attempts and it took - you guessed it - 3min 9seconds. I am running Ubuntu 8.04 LTS and have applied all of the latest updates for that version.
One thing I did notice was a proliferation of apache2 processes. With every request for a page I seem to get 7 or so new apache2 processes.
just upgraded to Lucid. When booting, I get a blinking cursor on a black screen for 30 sec. Then I get some flashes of text about UDEV. Finally, I get a desktop after about 30 more sec.
Any way to speed this up? I've already tried disabling my nonexistent floppy drive in the bios, but it didn't help.
Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.
I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....
how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps
xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm 1920x1080 60.00*+ 59.93 40.00
I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while
I have 8.04.3 server-32bit. It is on an HP 2.3ghz Pent 4 with 512 mb of RAM.I had previously installed Ubuntu and Kubuntu in a dual boot with XP (actually had a triple boot with XP, Ubuntu, and a BETA Windows 7) for a while, Grub got messed up so I ended up wiping it and just put my XP back on it. I have been intimidated by the command line and when thinking server, I tried the 30 day deal with windows Home server, its OK but it's $100.00 for the permenant version.
Anyway, I manned up to the challenge, installed Ubuntu server, set up as SSH and Samba. I administer from PuTTy and WEBMIN, I tried TightVNC but the GUI seemed very useless, so on a reinstall I went headless.The problem is I have alot of MP3 files I want to transfer back to the server that I had previously transfer to and back again from the Windows server, it was sceamin' fast compared to this. I have found threads talking about using NTFS, I have the EX3, or whatever the Ubuntu format is. Could that cause slow transfers, from NTSF through Samba to Ubuntu?
Today I installed Ubuntu server 9.10 on my old sony laptop with 512MB of RAM and 2.4GH celeron CPU. I hooked up my server to the router(D-Link) using cable. Now I try to upload or download data(mostly my music) to the server the speed is no higher than 500-700 KB/s. Although at first it used to be around 1.2 MB which is still considered to be low, but is there anyone who knows what I should do? By the way, I use SSH on Ubuntu 9.10 to connect to my server.
then I connect into work through a secure vpn connection that used to be reasonably fast. Sometime in the last year or so it has slowed down dramatically as if they added a one minute delay between pages. Everything works fine otherwise. It's just slower. At work they use all microsoft software, server software, etc. and if I connect in my friend's laptop with Windows 7 it works quite well and the pages load quickly like my Kubuntu laptop used to. What I'm wondering is if this is some kind of compatibility issue between Windows explorer and Firefox browsers or just a sour grapes issue on Microsoft's behalf where they slowed things down on purpose?
I have many openvpn implementations. Every time I use windows shares over openvpn, the speed is no more than 500KB/s, in LAN environment. When I start a copy it reaches 200-300KB/s, when I start second one it reaches 500KB/s. No more is reached after more copies simultaneously. When I use linux to copy files - the first copy reaches 700KB/s, the second copy reaches 2.5MB/s (then the first grows also to 2.5MB/s), the third copy reaches also 2.5MB/s. All of these are copied simultaneously, otherwise when only one is started it sits on 700KB/s. Moreover when 2 of the 3 simultaneous copy processes end, the one left backs at 700KB/s again.
But this is linux. When I use Windows the transfer speed is no more than 400-500KB/s (LAN environment). The OpenVPN server is always ubuntu (any version - I've tried 6.06, 8.04, 10.04).
Tried the OpenVPN client in ubuntu (and the windows machine behind the ubuntu), in windows (directly installed the client on windows) and it is all the same - no more than 500KB/s.
I can not use this because it is so slooow. When only one file is copied at a time it reaches only 200KB/s!!! Searched all the google results - no one have an answer, although there are many people with the same problem.
Now, I am sure that the problem is in Windows, because when I use linux as a server and as a client, the client copies fast. But when I use windows as machine behind the client it copies slow. I don't know... something in the tcp/ip settings in windows or something...
I posted this yesterday, but my post completely disappeared (I looked high and low -- nothing.) I am using Ubuntu Server 10.04, all the latests updates. For an FTP Server, I use ProFTP.
One specific directory, and it's subdirectories on my server will not download at a reasonable rate. They move at about 17-50KBPS. All other folders work fine, at around 1.5-2.5MBPS.
What is going on? I have no idea how to troubleshoot this. The files being transfered are in a directory under home. They should have no permissions issues (I reapplied the permissions I want already), I tried restarting ProFTP, the files vary in sizes (from a few kilobytes to about 120 megabytes). I use Webmin for most web management.
I am not having overload issues with my network card or CPU utilization while downloading these files. They are being accessed from the local network.
This issue is taxing because the files in question are backup files.
