Good to hear - I had access to a dual 1.25 GHz today, and benchmarked it 
using LAM with 1 & 2 cpus.

Unfortunately the shared-memory communication in LAM doesn't work on OS 
X yet since it requires
posix semaphores (and these don't work yet in OS X), so there is more of 
a speed hit than with linux.

I'll add the numbers to the benchmark page in a couple of minutes...

Cheers,

Erik
