kernel_task constantly using 5%-25% CPU

[Kona*]

Hi

Ever since I got my MBP I noticed that the process "kernel_task" was always doing something - constantly using between 5% and 25% of my CPU usage and usually around 400MB of RAM. Is this normal? I've had a search on Google but most issues are for kernel_task using 100% of CPU usage on MacBook Air's, nothing much about MacBook Pro's.

If this isn't normal, does anyone have a suggestion on how to track down what the problem could be?

Cheers

Well the kernel_task is basically the operating system (it's process #0), so it'll always be doing something, yes, but I've just looked at mine and it's using about 2% and 200mb RAM, so I don't know if that is a little bit high or what...

I don't really know past that.
