Hi Stratos,
Yes, your results show some improvements. BUT if performance is the only thing
we were looking for, then we will never use ondemand governor but performance
governor.
I suspect this little increase in performance must have increased power numbers
too (significantly). So, if you can get numbers in the form of power/performance
with and without your patch, it will be great.

I run some more tests. I increased the number of iterations to 100 (from 20).
I also test for counter 1,000,000 (~4200us), 5,000,000 (~10000us), 15,000,000 (~30000us).
This time, I also extracted statistics from cpufreq_stats driver. I think this will be an
indication for power consumption. Below the results and attached the program I used for to
get these numbers.
Any comments would be appreciated.
Thanks,
Stratos
