Performance drop from 4.13.10 to 5.0.1
Problem
Do you want to request a feature or report a bug? Bug What is the current behavior? After upgrading from `4.13.10` to `5.0.1` on production environment, we noticed a real performance drop in all requests using mongoose models : ~200ms per response. We didn't release any code change apart from the `mongoose` dependency upgrade. And we don't use any particular feature of mongoose apart from models & schemas. After applying a fix to revert to `4.13.10`, everything went back to normal. Deploying with `5.0.1` : Reverting back to `4.13.10` : If the current behavior is a bug, please provide the steps to reproduce. More of a performance issue than a bug, so I'm not sure I will be able to reproduce it outside of a production environment. If someone knows any way to benchmark this I will be happy to try 😊 What is the expected behavior? Having response times around ~20ms for 150 RPS. Please mention your node.js, mongoose and MongoDB version.* node.js 8.9.4, mongoose 5.0.1, MongoDB 3.4.10. If it's of any use, we are on a cloud managed (Atlas) sharded cluster.

Solution: Performance drop from 4.13.10 to 5.0.1
Interesting that both node and MongoDB times increased with 5.0.1. Are you able to isolate or narrow it down to a couple example requests that take significantly longer?
