KDE very slow in core2

[Patrice Brockhaus]

Hi!

I'm using a celeron 333Mhz an i'm very disappointed of the performance of KDE. 
The start-menu is almost unusable because I often have to wait several seconds 
for menus to pop up :-(. Works great with core 1. Anyone experienng this too? 
Can this be because of ext3fs? I'm using reiserfs whith core 1, but  I had no 
choice of reiserfs during instalation of core2 :-(.

Bye,
Patrice
