Dual core Int Benchmark instability — at Version 1

Reported by: KSMarksPsych Owned by: davea
Priority: Major Milestone: Undetermined
Component: Client - Daemon Version:
Keywords: Cc:

Description (last modified by KSMarksPsych)

On dual core systems (but not HT ones) the integer MIPS can vary dramatically. It was first reported by Tony on the ​alpha list which includes data from old core clients and different machines.

It has been further documented ​here.

Some recent data off my dual core machine (Vista Home Premium and Single User install)
