HO !

There's a serious problem with my setup, there is no doubt !

I make the test with xcompmrg.. withou I got 

320 reps @  22.1747 msec (    45.1/sec): ShmPutImage 500x500 square
320 reps @  18.4267 msec (    54.3/sec): ShmPutImage 500x500 square
320 reps @  16.9780 msec (    58.9/sec): ShmPutImage 500x500 square

I launch Xmach64 -dpi 100 -rgba rgb -screen 1024x768x24 -shadow +bs 
-3button -mouse /dev/psaux,5 


I'm running linux 2.6.6 on debian (kde3.2.2)

I'm interested in your configuration / fdo xserver... 
Anyone got a clue for me?

thanks in advance,

thomas.
