I'm using dell xpx L502X (i7 - core) with ubuntu 11.10 with nvidia 525 with optimus support. I have installed ironhide for optimus support on my laptop. When I look at system monitor even under ideal condition 2 - 3 cores out of 8 cores shows around 10% usage. Is this issue normal. How to resolve it if it is an issue.

Please guide me
