I have a Flask application and every time I reload the web app on Python Anywhere, it takes way too long (something like 10 minutes). After it finally loads, the performance is ok. But the same phenomenon happens again when I make a new request after a period of inactivity (presumably because Python Anywhere is temporarily deactivating the instance). I ran my app on the virtual env, and it shouldn't take more than 30s to load it, so it doesn't seem to be a problem with the code. What is going on?
