Pycharm run slow when toggling breakpoint in Debug mode

Question

I am using Pycharm (version 2018.3) to develop my application.

When running the script in run mode or debug mode, the script runs in about 5 seconds.

When toggling(enabling) breakpoint, it start to run very slowly(The script runs for like 3 minutes instead of 5 seconds).

Any ideas why its happening?

Answer 1

Are you using Pycharm 2018?

I had similar problem of slow run when moved to Pycharm 2018. More people experienced it here.

After returning to Pycharm 2017, it was stable again.

Edit: You can try 2019 now.
