Some update/fork to this subject...
On my search to get the "desktop user-experience" a faster one on my FreeNX 
(Debian) box, I came over 'prelink'. 
(This try to do what MS has been working on in the last years (prefetching); 
to make the startup of the OS and applications be as fast as possible, with 
the "HW as limit".)

I've experienced that this really helps on my Debian system, making both the 
login process and, generally, working with applications (like OpenOffice.org) 
and the window manager (KDE/Gnome) more faster. 

I haven't played much with prelink yet, so far all I have done is basic:

1. installed prelink ('apt-get install prelink')
2. 'prelink --all --conserve-memory --random'
3. edited /etc/default/prelink (changed 'PRELINKING=unknown' to 
'PRELINKING=yes')
....and presto! It helped! :-)

Just a tip from my side, but you people probably knows about this 
already.... :-)

PS! Anyone tried OpenOffice.org Quickstarter for KDE? On my system it resulted 
in some funny stuff with FreeNX.... If I logged in as the same user twice, 
OpenOffice.org Writer would (among others) start on the second session if 
closed on the first.... A session-bug in FreeNX, or a bug in the 
Quickstarter ?
