Importing `pdb` does not slow down the application significantly (it just adds the import time but does not otherwise affect the application). Only when you execute code under debugger control, the execution is significantly slowed down (because the debugger gets informed (via callbacks) about important "event"s (entering a line, function call, function return, exception) during the execution). Excellent, many thanks for confirming. I can leave the execution running then. -- https://mail.python.org/mailman/listinfo/python-list
Does loading PDB slow down execution?
Hi all, If I run a python3 program with "import pdb" in the code, would it execute slower than without loading the debugger? The program I am running is computationally expensive and mathematically orientated. It is expected to run for a few months (I am a few days in). I found out today that I forgot to comment out the "import pdb" while debugging, and now I am wondering if there would be a performance benefit worth restarting the execution with pdb unloaded. I have tried testing this with a simple sum executable, but I don't see a clear difference with short execution times (<5 mins). Before I investigate further, I thought I would ask and see if anyone knows the answer already. Many thanks! -- https://mail.python.org/mailman/listinfo/python-list
