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.

It’s still early days

Lemmy has been on GitHub since February 2019, over four years. It isn't new at all. Several instances go way back.

The answer is: ORM.

I don't mean the code is new, I mean the user base and data corpus are small compared to what we are hoping for. You're probably right about the ORM. :/
