I’ve experienced a lot of n+1 queries problems as causes for bad performance. Often times this was a result of wrapping the ORM in abstraction layers (for business logic and fears of being “locked in” to the ORM). We rewrote that part of the application using a different ORM (in Python). Making use of a tool that could help find these problems automatically helped greatly and we didn’t have a single performance problem when we went into production the rewritten service. This module can detect the n+1 queries problem automatically in Python ORMs: https://github.com/jmcarp/nplusone https://github.com/jmcarp/nplusone Looking forward to seeing more automated tools like this in the Python/Django world.
