James,

Thanks for the reply.

I see what you're saying.  Having multiple instances of MapServer taking advantage of multiple CPUs is great, just what I'm looking for.  Will this be done automatically?  That is to say, will new MapServer instances automatically use other CPUs, or does it require manual setup.  Perhaps Apache 2.0's multithreading abilities will handle this.

Thanks,
Xin

On the other hand if it's through put you need more instances of
mapserver can run simultanious om multiple CPU. That is you can serve
for instance two request at the same time, but the single mapserver
instance will not gain anything directly by multiple CPU's.
