Subject: Clear performance regression on reaim7 in 2.6.15-git6
Date: Sat, 15 Apr 2006 12:10:39 -0700	[thread overview]
Message-ID: <4441452F.3060009@google.com> (raw)

OK, looking back through the perf results, these two graphs clearly show
a perf regression in reaim7 from 2.6.15 to 2.6.16-rc1. We're loosing 
over 50% of the performance.

Drilling down (there's not enough detail on the graphs for releases that
far back), I see it's actually between -git5 and -git6

These are both ia-32 NUMA machines, one is an x440, the other is NUMA-Q.
