This exactly highlights my fear of widespread use of LLMs for code - missing the actual optimisations because we’re stuck in a review, rather than create, mode of thinking.
But maybe that’s a good thing for those of us not dependent on LLMs :)
Well if you or anyone else that has good optimization and performance chops http://openlibrary.org/ has been struggling with performance a bit lately and it's hard to track down the cause. CPU load is low and nothing too much has changed lately so it's unlikely to be a bad query or something.
Main thing I've suggested is upgrading the DB from Postgres 9, which isn't an easy task but like 15 years of DB improvements probably would give some extra performance.
It might not be as awful as feared? That big a jump probably requires a dump and restore, but maybe it could still be done in place. pg_upgrade is pretty solid. But I agree - it's likely a cheap and easy perf win.
Is there source code / a GitHub link with more information?
