[ltp] general performance question on R51

[Takis Diakoumis]

Hi

thanks for your response. i'm a little hopeful that i can fix it now.

i'm using cpufreqd for cpu freq scaling. i didn't change any of the
defaults in cpufreqd.conf - i did read it though and figured it looked
fine (bare in mind i didn't really know much about it).

no i don't absolutely need 2.6.11. i was using 2.6.11 debian kernel but
couldn't get the ir to work (module just wouldn't compile!). so i
compiled a vanilla 2.6.11 kernel. i will try a 2.6.12 one now that
you've mentioned it and see if it changes anything.

i have included some bits from my kernel compile .config file at the end
here - just the cpu and cpu freq stuff... perhaps i got something wrong
there.

thanks again.
