New Install running SLOOOOOOOOOW
Hey all,
I have a dual boot configuration using GRUB on my desktop PC. Dell Optiplex GX60, 2.40 celeron, 512 RAM, . The computer is only about 4 months old, so the hardware is fairly decent. I installed SuSe 9.1 pro a few months ago, and it has been really running slow sinces the first day. So I decided to start again and re-installed it again, same result. I have: Grub boot loader Windows XP Pro on the first partition The problem is this: Under any user, after I select to boot to Linux, it will take about 2 minutes to get passed the part where it shows the progress Icons. Then after the desktop background comes up it takes about an additional 3 minutes to populate the desktop with the task bar, icons. After everything loads, which is a total of about 5 minutes, it seems to be a little slow on starting apps, but seems to move a decent speed once I am in the app. i.e. web browser and so on. Any Ideas? Do i just need to tweak something? |
see if your dma is on:
hdparm /dev/hda you can also set this in yast also kde takes a while to start up it's a very heavy wm you could try xfce or icewm or another "light weight" wm |
Openbox and Fluxbox
I'm using Ubuntu 4.10 with a much older machine (PIII / 733 / 128).
GNOME actually loaded up very quickly. It would only start to lag badly when I was using Firefox with a few tabs open and trying to run some other program. Both Openbox and Fluxbox, while not as "pretty" as GNOME, are great window managers if you want speed. |
Lagging on faster machine as well.
Hey,
I read some other threads about machines "lagging" or pausing without I/O or 100% CPU. I have the following: Pentium 4 2.66GHz 512MB RAM 40GB HDD with DMA enabled Ubuntu Linux 6.10 (just installed it again) Just recently - before the reinstalling my OS - I noticed that selecting to run programs from the menus didn't start the programs until 1-3 minutes later. The CPU utilization was low and idling as if I hadn't selected to have anything run. No disk usage either, as my LED isn't flickering. For example, opening Firefox: 1) I go to Apps -> Internet -> Firefox 2) Less than 1 sec of disk activity 3) Many minutes of waiting around... 4) The harddrive starts grinding as it normally does when an app is loading to memory. 5) App is working. When I use these programs, they function as they normally do when open. However even after a cold start of Firefox, or XMMS, or Gaim, or the Gnome-Terminal the delay still persists. Any ideas? I'm stumped... :confused: -AM |
One possibility that comes to mind is the preemption model of the kernel (since I've just been messing around with that today). If it's set to fully preemptible, then it seems to make things start slower while being more responsive once they are running. So the voluntary preemption model is usually a better choice than full.
So if you could grep your kernel config (I'm not sure where it would be in SuSe) for PREEMPT to see if that's the case here? |
This is what I found for my system:
Code:
$ cat /usr/src/linux-headers-2.6.17-10/kernel/Kconfig.preempt -AM |
Here's something else to show what I mean (as an example):
Code:
$ time emacs The time is how long I'm sitting at my desk waiting, but the other times are how long my machine is actually taking to open up emacs, even after it has been loaded into memory... :confused: :confused: |
That file just shows what the options are. Maybe there's a copy of the config in /boot? or in /proc? Yes, changing it would require a recompile. But then I can't guarantee if that 's the answer here, 1m10.562s seems like more than just preemption would cause?
|
Here is something that seems to match your grep suggestion:
Code:
$ uname -r Code:
$ emacs -nw |
