Thanks for pointing out the tools. I will look in to them.
To confirm that i am measuring it right, can someone give some
(approximate) typical values for the above,
Assuming some 200 instructions in context switching  assembly code, i guess
the process context switch takes around 100ns. is this right?
I guess the process creation time will be greater than process context
switch time. correct?
Will the pthread context switch time be different from a kernel thread
context switch time?


thanks,
ramanan
