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 :) This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list [email protected]
