Talk:Operating System Design/Processes/Context Switch

I'm not sure that I agree with the claim in the box. Sure, User mode/Kernel mode swapping requires a context switch, but it's not the only reason. One User mode process being swapped out for a different user mode process may also require a context switch. And on a heavily loaded system performing lots of computation that might well be more common than system calls. --Zwack 16:39, 28 October 2007 (UTC)
