It's always a tradeoff, but I'm surprised to see so many people say that just because Python isn't fast it shouldn't get multithreading. Yes, by using Python we leave a lot of performance on the table. We also get a lot of dev performance, just because of the amount of libraries available, dynamic language features, quick development.. So it's not always a clear decision between Python or a compiled language. > If you need something to be fast you are supposed to use a C extension and control it with Python So what do we do with the case where we need to control the C extension from multiple threads? Because that's currently my problem. The C extension we developed do release the GIL, but because the Python code that does the calls to the extension can't be really multithreaded, the performance gain we get is minimal.
