My experiences have been the exact opposite. X has been a lot more responsive 
for me starting from Linux 2.2 and FreeBSD 3.x through Linux 2.6 and FreeBSD 
5. In fact, Linux 2.4 running KDE 3.0.0 was noticibly more responsive than 
FreeBSD 4.x running Window Maker (yes, on the same hardware). But I've also 
heard of other people having better responsiveness in X on FreeBSD. So I 
suspect this is more likely a case of YMMV between the two OS's/kernels.

Just thought that might be something worth noting.
