Haskell Profiling and Performance tuning

We would like to optimize the performance of a large scale backend system written in Haskell. Our load testing results are not great and we think there is an opportunity to profile and improve performance by at least 3X.



We are looking for someone who has experience with optimizing Haskell applications for high scale production use.



Our stack uses:

- Servant web server

- Beam for MySQL integration

- Aeson for JSON encoding
