I'm not talking about 32-64 copy of the same process.
100 process is nothing!
I was referring about having 10.000 - 40.000 process runnning
for a total of 60-90 GB RAM

My ---initial testing--- between a 4x880 Opteron and SF4800 12x USIII 1200 Mhz 
are showing lower load on the SF4800 when more than 10.000 process running.

Anyway doing benchmark is not easy :)
