No, I havent tried it without K. The system is quite responsive if I only run
updatedb, and swap around in either text-linux or a simple X setup. When
looking closer at the problem, it is the combination of running kmail with
HUGE folders (think linux-kernel archive), apt-get and anacron that thrashes
the system. All of these have a "relative" low impact when running alone or
two and two.
It might be "what you expect" abusing the system like that. But as I said, it
is not a problem in 2.4.11-pre1 and 2.4.12-ac3.

Does all this help you?

Notice this is not worst case, just what I could reproduce by starting
updatedb and checksecurity while answering your mail. Switchtime from desktop
to desktop is 1 minute.
