Hey Mark,

What sort of usage are we talking?  Web hosting?  Shapefiles and arials? 
  I'm not sure if mapserver itself will use mult-threads, but if you 
have multiple requests comming into a website, apache/cgi/mapserver/etc 
will use multi process/threads/etc.

Its tough to say the performance increase.  I'm host several maps on a 
dual-core box, and the cpu's sit around 2 percent.  And with lots of 
arial imagery you might hit disk io limit before you hit cpu limit. 
(However, I have had some mrsid files that were really cpu intensive to 
uncompress, they were cpu bound).  Are your cpu's even pegged?

So, I guess, the answer is, it really depends on a lot of different 
variables.
