Re: Performance issue since 3.2.6

[Olivier Doucet]

Hello,

A quick update on my latest tests :
I was able to compile a working 3.7.1 kernel (by 'working', I mean
with no performance penalty). I'm sure 3.7.7 will be OK also (do you
want me to test latest RC of 3.8 ?)

I had to disable CONFIG_ACPI_PROCESSOR to disable power management.
So now these two options are unset :
CONFIG_CPU_IDLE
CONFIG_ACPI_PROCESSOR

I've posted the whole .config file here :
https://gist.github.com/odoucet/4773390

I'll be glad to test any patch that may help reactivate PM on my
system (CPU Intel Xeon L5630)

Olivier
