Re: high load, but also high idle

OK, I realized the following.

I had been updating from 7.3 to 9.
The update did not work, so I installed 9 anew. I changed the root 
partition. Now the root partition was on the same harddisk as my data 
partition.
On my data partition I was multiplexing films.
With 7.3 this was no problem: Reading and writing about one gigabyte 
from and to the same harddisk. All Programs and other stuff was started 
from another hard disk.

But with the root partition on the same harddisk like this 
gigabytemovement the systems sucked.

Now I moved the rootpartition to another harddisk again and everything 
is (rather) fine.

Cornelius
