How to measure execution time of a multithread loop

[spacedog]

I have a small app that does work on about 100 loops each on a new thread. How can I measure the total execution time from the point where the app started to run to the point where the last thread completed?

If I do a print(endtime - starttime) after the last loop, the threads are still running for about 10 seconds. So the end of the last loop is not when the app is finished running.

Thank you.

You can use time.perf_counter() to get your start and end times, but timeit() may be a better match for what you want to do. See the docs

Thanks. I will look into that.
