kwin is slower on intel cards. Kwin with gnome or xfce is much
faster... Intel video cards are very slow...

From my experience every version of kde above 3.0 is slower than any
other window manager (gnome (sawfish, metacity, enlightenment),
xfce(xfwm), compiz, lxde,...), on every machine I've had. It needs more
memory, faster hard disks, stable filesystem (ext4::delalloc?), better
video card... and so on. Even Qt seems to be slower than GTK+ if you
launch application that does similar thing.

...or it's just my imagination :)

If you want smooth kde get a nvidia or ati card, at least 256MB, 2GB
ram, 1.6GHz.

You could also try nice/renice
