My module memory_profiler is capable of printing a line-by-line report of memory usage and works on Unix and Windows (needs psutil on this last one). Output is not very detailed but the goal is to give you an overview of where the code is consuming more memory, not an exhaustive analysis on allocated objects. After … Read more

However, if you’re in a hurry and you can manually interrupt your program under the debugger while it’s being subjectively slow, there’s a simple way to find performance problems. Just halt it several times, and each time look at the call … Read more
