The project got some traction, over 5k requests since I posted this. Probably the DB state needs to be optimized a bit. Thank you for reporting! I really appreciate it

Edit: I don't see slow traces in Sentry. No idea what caused this. Also, voting goes through redis and the dB load is low. Weird. I probably have to add gunicorn workers.

Edit2: Bumped gunicorn workers from 2 to 4. Should be fine now, under the current load. Again, thank you for reporting!
