 "Ultra high speed CPU: AMD K6-2+ at 550 MHz" - hmm, what is an AMD64 Hammer 
at let's say 1800MHz then :) ?

 Anyway. At least some of the results in your tests don't look right when 
comparing the KDE results to the GNOME results. I'd believe KWrite needing 
double the amount GEdit needs, or even tripple, but 5 times longer seems 
wrong. The same way KWrite should not need 15 seconds if Konqueror needs only 
2 (although this must be preloaded Konqueror instance).

 I have an old K6/188 available, which should have rougly just a third of the 
power of your machine, and I run KDE on it from time to time. I don't 
remember the times exactly, it is certainly sluggish, but at least KDE 
startup time is definitely less than 80 seconds, the other times may be 
probably roughly the same, perhaps slower, but I doubt it'd be three times 
slower than your numbers.

 Which means there's probably something wrong with the setup. I recently spent 
some time extensively profiling KDE startup, I'm about to finish updating the 
KDE performance tips, and I'll publish them shortly. I suggest you check them 
after they're announced, maybe you'll find the reason for your slowness.

 And no, performance has not been forgotten. If yes, I wouldn't have done the 
profiling, and others would have done the various optimizations either. It's 
generally perceived that KDE performance has been constantly improving with 
each new release. However working on optimizations is a tedious and 
time-consuming work, and moreover you cannot expect KDE to run acceptably on 
very old hardware like my K6 or to match the performance of old software 
developed for such hardware.


 PS: Oh, and yes, the very first tip in the tips will be getting a fast 
machine. That's the most reliable way of getting things to run fast.
