In linux 2.6.9 kernel (vanilla) I got better response time by increasing HZ value:
Is it harmless if I increase HZ value some more??
Increasing HZ means your CPU spends more time handling the timer interrupt, and has less time to run programs. On a laptop, it also means lower battery life.
Other than HZ, what are other params could I change (USER_HZ etc)
I would stay away from USER_HZ, otherwise you're going to have to recompile a whole bunch of userspace programs... -- What is important?
