Gunicorn+Flask+Nginx+VK Api - slow request processing?

Question

Nginx

There is a Flask-powered bot that proxies through Gunicorn+WSGI. The settings for the Gyunicorn are as follows:

gunicorn --workers 40 --bind 127.0.0.1:9250 wsgi:app --worker-class gevent --timeout 30

The bot is used by a huge number of people at the same time, but it processes requests too slowly. In the community control panel, it constantly displays the error "Error: Timeout was reached. Attempt 2/5". Errors from the python side are fixed and are not displayed. However, requests are still processed slowly and, as it were, in "packs" - the bot will immediately answer all the people who have the old message hanging and go silent for a minute.
In which direction to dig, tell me?
UPD: pymongo is also used, which consumes a lot of resources, judging by the top command.

Answer 1

Well, you need to read the python and unicorn ngix logs
