lemmy_server uses the Diesel ORM that automatically generates SQL statements. There are serious performance problems in June and July 2023 preventing Lemmy from scaling. Topics include caching, PostgreSQL extensions for troubleshooting, Client/Server Code/SQL Data/server operator apps/sever operator API (performance and storage monitoring), etc.

yes, I tossed together !lemmy_helper@lemmy.ml to bypass the API and look directly at PostgreSQL.

lemmy.ml is having real trouble getting messages out to peer servers.

I created a discussion forum on the lemmy-helper project for server operators / developers looking to discuss performance: https://github.com/RocketDerp/lemmy_helper
