You're using a laptop. So I guess you're just another use like me. You won't be
running database daemons or other server daemons on the laptop.

All I can suggest is to recompile your kernel with the following features:
1) Use 1000HZ for Kernel Timer Frequency (I highly recommend it)
2) Enable Kernel Preemption for Low Latency Desktops
3) Use "Preempt The BIG Kernel Lock"
4) Use CFQ as the I/O scheduler

Wish Debian shipped a laptop specific kernel like linux-image-X.X.XX-laptop
I've also been willing to do this but don't have the proper resources.
