Strange Performance problems

[Nils]

Hi all

I have strange performance problems on a box running Feisty. When I
run CPU intensive tasks, it's very slow. For example if i try to
install a package that is already installed it's stuck when "Building
dependency tree", which is a CPU intensive operation.

root at slowhost:~# time apt-get install lsof
Reading package lists... Done
Building dependency tree
Reading state information... Done
lsof is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

real    0m27.042s
user    0m26.520s
sys     0m0.160s


However on a machine with almost the same hardware it's  very much faster.

root at host:/home/creative# time apt-get install lsof
Reading package lists... Done
Building dependency tree
Reading state information... Done
lsof is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

real    0m1.091s
user    0m0.610s
sys     0m0.040s

This is just one example, logging in is slow, opening a new terminal
in screen is slow too, when I type ":sy on" in vim, i have to wait a
bit too, etc

So far I checked the hd and it seems ok (eg dma enabled, performance
tested with hdparm seems ok)

I also checked the temperature of both hds and it was below 30c
celsius. However I could not check the temperature of the cpu.

What could make this box soo slow.

I attached some info below, tell me if you need more.

Thx and Regards

Nils
