Berried Question
Hi all,
I think my question got berried in the list so I like to add some more info
and ask again.
One of my two Debian installations is very slow.
On the bottom I have added the output of top & the output of hdparm.
Intel 1000 MHz, 1000Mb Ram, 40 + 20GB HD
The slow machine:
Intel Celeron Processor 1 GHz
100 MHz System Bus
256 KB L2 Cache
Amptron PIII-3758TLM Board v 5.2
MicroATX with SiS630eT Chipset
Kernel: I have tried many.
At first I did not know if the problem was with the hd speed the memory speed
or the CPU till I found out that it was the CPU load, meanwhile I have tried
following installations with no change in speed
1) Regular of the newest Debian CDs
2) using Knoppix hdinstall 2.4.22-xfs then upgraded to the 686 Kernel did not
use xfs
3) using Morphix hdinstall with kernel 2.4.21-xfs and used xfs file system
4) using Morphix hdinstall with kernel upgrade to 686-smp but did not get it
to work
5) running now Morphix hdinstall with kernel 2.4.21-xfs but not with the xfs
file system
The problem is the CPU load when idle it runs between 5-30 %
As soon as I start an application it goes up to 100% and stays there till
the application is done loading. Loading an application like Kmail takes
about 2 to 3 minutes.
