I'd like to reproduce your results so I can make a new
version of the ptc.g patch that doesn't have this regression.

I found this version (that claims to be the latest) of hackbench.c

http://people.redhat.com/mingo/cfs-scheduler/tools/hackbench.c

Is this the one you used?


What was the configuration of your machine (how many cpus, how
much memory)?

Thanks

-Tony
