Why did the server response time (nginx uwsgi) increase?

Question

Django

I noticed that the server response time for a Django site increased from 0.4 to 0.79, why could this happen and how can I speed up the server?

Answer 1

1) look at the nginx and django logs to understand where the time is being spent
2) profile the code, most likely a new "heavy" query has been added to the database.

Answer 2

Try clearing the caches. They may not work efficiently.
