CPU usage

general

Hi,

I'm new to Xen, so pardon my lack of knowledge on the subject -

when I'm viewing CPU usage in "top" - 2% for a process, for example - is this the 2% of the allotted to my node right now, or it is always 2% of the whole physical processor?

Thanks!

Your Linode.

As I understand it if top shows a process using 40% CPU on a Linode, that means 40% of one of the four (virtual) CPUs available to you, or 10% of your Linode's total parallel processing power.

You are correct. You can confirm this by pressing "1" after you are in "top" - this will toggle displaying the CPU usage of all 4 cores.

Cool. I need to go and read the man page and see what other tricks I've missed.
