Hyperthreading and SMP

[Kenneth Porter]

Does WINE have any problem with either Hyperthreading or SMP? I've found 
that locking the Tribes Vengeance dedicated server to a single logical CPU 
seems to give me better performance as the server fills with players. CPU 
usage seems significantly lower (45% versus 65%). Is this likely to be a 
WINE issue or a TV issue? (TV is based on the Unreal Tournament engine, 
with the Havok physics engine integrated to handle vehicle. Alas, unlike 
UT2004, there's no native Linux server for TV.)

I want to try disabling HT or setting affinity on my co-admin's Win2003 
server to see if he sees the same boost.
