I'm curious about the performance of the 4-way and 8-way systems. I know
nothing about this benchmark. IIRC correctly it simulates chat clients
connecting to a server and talking to each other. Is it a CPU, memory, or
disk bound benchmark? What is causing the 4-way machines to be only 2x the
performance of the 1-way machine and the 8-way machines to be < 3x the
performance? Is the system bus the limiting factor on those machines?

Curiosity aside, it looks like Ingo's scheduler is coming along nicely.
