a very clintonesque definition indeed ;-)
what is relevant is the latency to switch from one process to another one. And this is what we call a context switch. It includes scheduling decisions and all sorts of other stuff. You are comparing stack & caller-saved register switching performance (which is just a small part of context switching and has no standing alone) against full Linux context switch performance (this is what i quoted), and thus you have won my 'Mindcraft benchmark of the day' award :-)
