no, I meant kilobytes.

And swapoff really helps.

Some moments of disk activity, and bang, computer is as fast as always again.

But having stuff in swap? konqueror is slow, kmail is slow, opening a konsole 
session, slow. Everything crawls with lots of disk access. 

next time the computer is slow, I could gather some data - if you tell me, 
what is interessting for you, I'll save it.

Glück Auf,
