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
