I am installing Red Hat Linux enterprise 5.0 on HP proliant ML 110 G5 with X3330, 8 Gb 2 X 250gb SATA Config. Time required for full istallation is around 2hours 30 minutes. What could be the reason?
View 3 Repliesok, we had to move one of our databases due to failing hardware. This box is newer than the old but it's just dog slow. 1st I thought it was mysql but now I am realizing it's the network. As a test, I tried copying a remote file to that box and the old server (located at the same co-lo, same provider), same switch, etc.Here are the results;
Old server:
access_log.1 100% 4192KB 1.4MB/s 00:03
New Server:
access_log.1 100% 4192KB 72.3KB/s 00:58
So now I see why people were complaining about webpage load times, etc. I can't figure out why the network latency. I looked around a bit, see below for some things, I thought mtu, nic speed, etc.
mii-tool shows;
eth0: 100 Mbit, full duplex, link ok
eth1: 100 Mbit, full duplex, link ok[code].....
Are there other things I can type to test or provide more feedback somehow to get more information.
i'm trying to run ubuntu 8.10 intrepid ibex on an old hand-me-down laptop that i got from a family member, and i've noticed that the performance is actually much worse than it was on windows xp professional (32-bit).
first of all let me give you my specs:
ibm thinkpad r32
intel mobile pentium 4-m 2.0 ghz
ati radeon mobility m6 (i think this is actually the mobility radeon 7000 igp) with 16mb ram
256 mb ram (pc-2100)
i understand that these are very low performance specs, but it feels like the computer is running very sluggishly even for those specs. the computer ran just fine in windows xp, but is extremely sluggish in ubuntu. it seems like it detected all the hardware just fine, but i feel like it may not be utilizing the cpu and/or video to the extent that it should be. a couple of places where it really seems to struggle is when first opening new programs, viewing flash intensive web 2.0 type webpages (i.e. videos), and listening to music/podcasts (with rhythmbox).
it seems like rhythmbox really kills my performance more than anything else, but the performance is poor all around compared to xp, and i feel like that shouldn't be the case. like i said, i understand that the specs are poor, but it feels like it's not even living up to those specs. i know that 8.10 is old and outdated now, but it's what i had laying around and i figured that it might perform better on this old deprecated laptop than 9.10 would anyway. am i wrong in this assumption? would 9.10 perform better for me?
I am running karmic and have wireless performance which is terrible on the EEE 1000HA I see it as low as 1mbit at times and others at 24mbit and briefly at 48 and 54mbits. running an Internet speed test with wireless I get pathetic speeds as low as 15Kbps, Its 5 feet from the wireless router ... and other machines that are wireless in the same area show 54mbits and perform great ... any one solve this problem with the asus EEE1000HA running on karmic?
View 1 Replies View RelatedI just installed Ubuntu 10.04 on a laptop that was given to me. It is having a lot of lag issues,especially when playing videos and visiting websites using flash. It's an Intel Pentium 4 2.4GHz machine. I think that it should perform better because I had used and AMD Sempron 2.0GHz machine with Ubuntu before and video playback was much better than this. I'm thinking that my problem is the graphics card driver. Here is the card that this machine has:
Code:
:~$ lspci | grep Radeon
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP 330M/340M/350M
The AMD machine was using a VIA graphics chipset.
I used the command "Xorg -configure" to create a xorg.conf file, hoping that might help. But it didn't. Here it is:
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code]...
Is there any tweaking that I can do in the xorg.conf that might help? I don't know which of those options I should set. I also tried changing the driver to "ati" but that did nothing. found some info for settings with "man radeon", I'm going to try some of those out.
I have an ATI RADEON 7000 (taken from lspci) 64 MB graphics card. My computer has a 700 MHz Celeron CPU and 650 MB RAM with Ubuntu 10.04. Anything graphical is slow. I cannot even play basic games like SuperTux. I think it is a graphics driver problem. Will this card ever work well with Linux, what do I need to do?

I experience very poor desktop performance on my system. General clicking responsiveness is poor, taking over second or two to focus to a new window, move windows around, ... etc. The Xorg process constantly uses over 60% of the CPU even when I'm doing nothing, and when I do click around it will quickly go up near 100% usage. Performance is initially OK when I first launch into my Gnome environment, but it soon deteriorates within 30 minutes or so. Eventually, after days of being up and running, my desktop will crash.I am running Ubuntu 10.10 with latest upgrades. I have four monitors attached to my "nVidia Corporation G98 [Quadro NVS 420]" graphics card. I am running the "NVIDIA accelerated graphics driver (version current)" recommended in the Ubuntu "Additional Drivers" app. I get a fair number (hundreds) of these in my /var/log/Xorg.0.log:
Code:
[862923.098] (WW) NVIDIA(2): WAIT (1, 6, 0x8000, 0x0000ba04, 0x0000ba14)

though they don't appear constantly while my desktop is running (I assume they may come in batches?). Not sure if they're relevant. A separate issue, though possibly related, is the SpeedCrunch app (a desktop calculator) is guaranteed to crash my desktop as soon as it gets focus. Here's the relevant output of "lspci -v" which shows my graphics card:

I've just removed fedora 10 and installed CentOS 5.4 both x86_56 on my Lenovo ThinkCentre 9091-CTO workstation, and observed serious performance degradation while intensive I/O operations and huge load without significant CPU consumption in user mode with about 50% in I/o wait.For example if I do the "tar xjvf some_large_tar.bz" file and run vmstat i get the output below. This is the only cpu and io intensive process running. The load gets up to 6 on C2D CPU and the machine has unacceptable responsivness.

So for the last, oh, three or four hours now, I've been trying to get videos to play properly in Ubuntu. I have the default player, I have vlc, I (apparently) installed mplayer, but it won't play anything at all.
I was having horrible screen tearing with standard definition .avi's in vlc, fixed that by setting vsync in catalyst control center to always on or whatever it is.
Now, I have tried to run a 720p x264 video. It PLAYS, but not well. Audio is fine, however video is all jerky in VLC, and in Totem it's just a mess of screen tearing (although the video does no jerk on that player).
I have just spent HOURS trying to get VIDEOS TO PLAY. This makes no sense. Playing a video should be the simplest thing in the world for any OS to do, but with Ubuntu it is like pulling teeth. I have NEVER been so frustrated while using a computer. What is going on here?
BTW, I installed every single thing needed to use mplayer but it still does not work. The player comes up but will not play any type of file.
My system specs:
2.2Ghz dual core (intel)
3gb ram
1GB radeon hd 4650 vid card
asus ipibl-lb mobo
I was really enjoying Ubuntu until I got around to trying to watch some videos. Now I am maybe minutes away from going back to vista. At least on there I can watch full 1080p videos if I want with no problems.
I am running kubuntu 9.10 on a dell inspiron 14 with an intel GM45 graphics card. When I run 3d games like Nexuiz, openarena and tremulous I get really random performance. Sometimes things are totally playable with somewhere between 50-80 fps and other times I get maybe 4 fps and everything takes forever to load. These effects persists between logouts, X restarts and reboots! I get no errors when I run things in console either.I never really play games much but when something doesn't work...

I have a HP dv6314tx laptop with Nvidia Geforce Go 7400 graphics card. Recently I installed 10.04. Without installing any nvidia drivers my boot screen resolution and desktop resolution were fine.

But during the boot, the splash screen has a very poor resolution.
View 2 Replies View RelatedI wanted to install the latest version of the Revolution Enterprise R 4.0 software on Linux, however the company only supports the produce on Windows and Red Hat(CentOS). Since I don't want to stay on Windows and CentOS is too locked down, I was wondering if I could install the Red Hat version of the RPM on Fedora? I am not sure if there are any particular issues associated with installing Red Hat RPMs on Fedora with respect to compatibility.
The company said that they do not support Revolution Enterprise on Fedora yet and have not tested it. Since the software is proprietary--I can get it under a free academic license--I cannot compile it from source. I tried to install the software in a Fedora VM, but it seemed to quit in the middle. But that might have been just my lack of Fedora experience more than a software issue.
I hav successfully installed RHEL5.1 on my system. I downloaded flash player from Adobe website. I chose RPM from the download type. Now, I can find an icon on my GUI for the flash player. When I right-click the icon and click on "Open with software installer", I was able to install flash player. Even the system showed that the software has been installed. But still when I issue the command rpm -qi flash the output says that flash is not installed.
Is there any correct way to install the rpm package. I even tried to install using rpm -ivh <flash player pkg name> even that did'nt work... I have another query... where does the package gets installed when I download RPM's or any other software from the internet.. I want to know the path where the pkgs will be sotred...

View 1 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?
