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 switch time ?
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
