See also: !lemmyperformance@lemmy.ml community, it's not always clear which one to put a topic into. "lemmycode" I'm trying to be more into actual code change proposals.

Lemmy_server & lemmy-ui deliberately run with very slow PostgreSQL to shake out all the code error logic, nginx 50x errors are happening because the Rust & NodeJS code isn't graceful (lemmy.ml)

This is over a decade old, but the general idea here is to do what you can to simulate overloaded database so that the Rust and NodeJS code is tested to gracefully report to the end-user (and log to server operators) that the database backend is failing.

Lemmy has been falling over to nginx 50x errors under overloads, denial of service situations. Try to exercise the error behavior and harden the Rust and NodeJS code.
