It seems the lots of people are scared to have more than one thread, wonder why?

Actually I'm curious if anyone have hyperthreading computer, or dual processor one? And how looks JVM on it? Stop the world as always  Wink or some nice smooth... well you get the idea.

My experience of multiple processor machines and Java has been great.  The multi-threading splits out great by the VM on Windows2000.

Dual processor NT systems running Java are really nice. You only get about 5-10% performance increase by splitting rendering and logic up into two threads but the garbage collection pauses completely vanish if you use parallel incremental collection.

In fact I'm about to do some more live TV graphics, and we run our rendering server on a Win2k dual 1GHz box so we don't get any dropped frames.
