i came accross this issue and i found some good documentation about it. I thought i could share with you. Have you looked at the CPUfreq subsystem in linux? if not please visit this page
http://www.kernel.org/pub/linux/utils/kernel/cpufreq/cpufreq.html
/linux-2.6.18/Documentation/cpu-freq/

Dear All,
Please look into this if you have free time.
In linux 2.6.9 kernel (vanilla)
I got better response time by increasing HZ value:
1. with 1500 for HZ -----> < 2ms response
2. with 1000 for HZ -----> < 3ms response
Is it harmless if I increase HZ value some more??
What would be the maximum value for HZ:
Currently I saw 15xx maximum limitation for HZ.
How can i over come that limitation?
Other than HZ, what are other params could I change (USER_HZ etc)
Thankx in advance!
