In light of your message, I was provoked to switched my workstation at 
work to using the sched_ule thread scheduler. I do not have remote access 
set up via a graphical interface, so I can not test anything yet as far as 
KDE is concerned. However, I have noticed a performance increase with an 
ssh session into my workstation. Whether this is psychological or not, I 
doubt as I have become sensitive over the years to network speed.

I am running on a dual Pentium III system:

   duane# grep CPU /var/run/dmesg.boot
   CPU: Intel Pentium III (999.67-MHz 686-class CPU)
   FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs

Nothing else has been altered from default settings as far as any make 
files or anything else. This was a complete install from scratch.
