with single head, agp+dri it is acceptable... but still 1m slower than
2.4 (also noticable on the 100% filled sysload applet).
real 5m10.619s
user 0m1.367s
sys 0m13.029s
(btw these are 254665 files)
I really wonder what changed from 2.4 to 2.6 to make the same X config 8
times slower... w.r.t. terminal speed.
