What's the advantage of running multiple threads per UWSGI process?

阅读更多关于 What's the advantage of running multiple threads per UWSGI process?

问题 If I'm performing blocking operations like querying a database, then what is the advantage? How does this add extra worthwhile capacity? 回答1: Python's native multithreading is affected by GIL limitations. Simply put, only one Python thread at a time is physically executed. An exception to this are blocking IO calls (e. g. DB query) that let other Python threads take over, which may increase performance of IO-bound operations. So the real performance gain would only be possible if your
