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.

lemmy-ui seems to be doing database search for Post Title matches while typing every single character or edit, for performance reasons suggest an option to disable this feature be available to admins (lemmy.ml)

My concern is that Lemmy is not scaling and was not tested with enough postings in the database. These "nice to have" slick UI features might have worked when the quantity of postings was much smaller, but it puts a heavy real-time load on the database to search postings that keep growing in table size every day.

I also suggest that this kind of feature be discussed with smartphone app and laternate webapp creators - as it can really busy up a server dong text pattern matches on all prior posting content.
