creation, context switch time of process and thread

[Srinivas Ramanan <srinivas.ramanan@xxxxxxxxx>]

Can someone give the �information of following typical values in Kernel 3.x

in a 2Ghz machine with sufficient RAM

Process creation time ?

Process context switch time ?

pthread creation time ?

pthread context swich �time ?

kernel thread creation time ?

kernel thread context swich �time ?

What is the best way to measure these values?

I wrote �a simple test for measuring�kernel thread context switch�

A simple test like

1. get_time(start)

2. schedule();

3. get_time(end)

4. print( context sw time = (end-start) )

But it doesnt seem to work correctly.

Thanks.

Ramanan
