Method and apparatus for analysis of thread latency
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.
Abstract(Chinese):

用于分析线程等待时间的方法包括：确定感兴趣的线程; 计算感兴趣的线程停留在运行队列中以确定线程运行队列时间的时间段的总和; 计算时间周期的总和，其中感兴趣的线程被其他线程抢占以确定线程抢占时间; 并根据线程抢占时间对线程运行队列时间评估所关注线程的线程延迟。
