Webb5 mars 2024 · 1. The answer depends on your OS and settings. If you are using Linux with the default process start method, you don't have to worry about duplicates or process communication, because worker processes share memory! This is efficiently implemented as Inter Process Communication (IPC) through shared memory (some more details here ).
