Profiling requests

Once you have a development environment set up, you will need to launch OctoPrint using serve --debug as parameters.

At this point, you are able to make the exact same requests as before. To profile a specific request, just add ?perfprofile or &perfprofile to the request parameters. The request will be rendered as usual, but you will receive an html document with the profiling results instead of the contents of the response.


If you receive a 500: Internal Server Error and a ModuleNotFoundError: No module named 'pyinstrument' in the console, you didn’t install development dependencies. Do that now using pip install -e '.[develop]'.
