I did not make any comment as to the speed of KDE 4, as I don't use it myself. 
I too am in love with KDE, as far as version 4 is concerned I'll decide once 
it's ready for use.

My point was just that I don't know why users know so little about how a 
computer works to expect that installing a new version, plus turning on all 
the gizmos that heavily use memory and 3D graphical systems and be surprised 
that an older system gets slower - it's just what everyone should expect.

The question why 4 is slower than 3 on a system that should run it smoothly 
should be answered by a developper. OS X 10.5 is not faster on every system, 
nor is Vista. People tend to believe that a new version is (always) better 
than the previous one, they are wrong. KDE 3 has been tuned and bettered for 
years, KDE 4 is new and still work in progress. So we come back to the 
problem that a beta version is branded 4.1.2...  If it was "beta", the answer 
would be  to wait for the official release, but as 4.1.2 *is* an official 

And all this said, I too appreciate the work of the developpers. Probably in a 
few months (years?) everyone will praise KDE 4. Just wait.
