Abstract: A method for analysis of thread latency includes: determining a thread of interest; computing a summation of time periods in which the thread of interest stays in a run queue to determine a thread in-run-queue time; computing a summation of time periods in which the thread of interest is preempted by other threads to determine a thread preempted time; and evaluating thread latency of the thread of interest according to the thread preempted time to the thread in-run-queue time.
