How To Measure Time In Kernel Space. I know nanoseconds are not really precise but i need more precision than. I am currently using the do_gettimeofday() function to measure time in the kernel, which gives me microsecond precision. Understanding the cpu time spent by process in user/kernel space. Is there way to determine using standard linux/unix tools how much a process has spent in user mode and how much waiting for kernel? The kernel can only measure the time span between asking the hardware to enter an idle state and the subsequent wakeup of the cpu and it. It measures time taken for each recv with something like: The output will look like: I want to measure time intervals in my kernel. Add time before the command you want to measure.
