I have a venerable PIII 450 ,geforce 2 graphics card and a 2.6.x kernel 
(Debian).  When I maximize a hidden window it pops up instantly.  It does 
take 0.5 seconds to open a new Konsole but Konqueror only takes 0.25 sec in 
file or browser mode.  Kontrol center takes 1.5-2.0 seconds to load the first 
time, 1.0 sec afterwards. I can't notice any repainting of the window 
contents (one exception for me are complicated Scribus docs).  KDE is 
snappier on this machine than the original Win98 that it came with.  Open 
Office takes 50-70 seconds to load the first time :( but about 7 seconds on 
reloads (not using the quickstart utility).
  If I run gnome instead I find it to be a little slower (just my impression) 
and certain themes can't be used because of the re-draw rate of some widgets. 
Other themes seem fine.  The two desktops are pretty comparable with in my 
mind a slight edge to KDE.

There seems something else going on.  Try a different driver for your ati 
card.  Check your network setup - perhaps Konqueror is trying to access 
something unavailable.  Not much help, I know, but KDE should be much faster 
on your machine.  Laptops are always a pain to configure.
