what do your database and server logs show? are there slow query timeouts, deadlocks, etc? are these happening during peak load? 10-30 seconds looks more like an issue with competing locks or available workers, than potentially pool checkouts or lazy loading.
aside from db logs, i've found statsd very useful for debugging these sorts of things. we log both requests count/timing and hundreds of points in our codebase as well. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
