That's here the same on a cold boot because the disk access is the
limiting factor and therefore your numbers are what I normally get
too (one kde session until shutdown). 

In the case I login/logout/login (tests/reconfig ...), and
verything is in RAM (_no_ disk access according to led here!)
I see a big effect if ICE-unix is owned by root or not.  With
ICE-unix chown root, after login I almost immediately see the
kdesktop & ksplash on the first or second last item indicating
that the apps are restored.

That's on a laptop with 1.4 MHz Pentium, 512 MBRAM. I've seen
the same effect on a 4 way sunserver via an X-terminal.

As soon as disk access is involved the ICE-unix slowdown is
