This is one point we are actively working on all the time.

When Discourse was new, almost all sites had a brand new database so the database could fit in memory easily. Now, a few years later, some sites have over 100GB databases and RAM sizes that are not even a tenth of that.

One upcoming update in the next few weeks is the PostgreSQL 13 upgrade that will reduce the largest object size in half.

Other than that, step 0 into debugging your performance issues is gathering data with [Prometheus exporter plugin for Discourse](https://meta.discourse.org/t/prometheus-exporter-plugin-for-discourse/72666) so we are not flying blind.
