Depending on your node, you may want to limit it to 20 processes.
Context switches are expensive (relatively) and with that many
threads/processes active you're going to bog rather quickly.
Hyperthreading may help you a little bit, but it's still got shared
busess/caches.  Moving to a clustered system using LVM or something
may alleviate some of this since processes are distrubuted over the
nodes in the cluster.  Running true-dual or Xeon quads will help as
well.

If you want to support 8-10k active processes, I hope you've got
some serious cash to toss around.  *grin*
