We would like to know the time a context switch in UNIX takes.
Is there any way to measure this? Is it documented somewhere, 
say for SunOS 4.0.3 on a Sparcstation 1+? How does this figure
vary as a function of # of processes? 

Also, any tips on how to take fine resolution performance
measurements within UNIX would be a great help to me.

Any input from informed netters would be extremely valuable.
Please email me at:

Thanks in advance.
