I don't think anyone advocates sacrificing UP performance for 32 ways, butOn the Scalable Test Platform, running osdl-aim-7, for the
as he says it can happen .1% at a time.
But it looks like 2.6 will scale well to 16 way and higher. I wonder if
there are many regressions from 2.4 or 2.2 on small systems.
UP case, 2.4 is a bit better than 2.6, this is consistent across
many runs. For SMP, 2.6 is better, but the delta is rather
small, until we get to 8 CPUS. We have a lot of un-parsed data from other
tests - might be some trends there also.
