Yesterday some major server operators were talking about federation performance.

Database and client API performance… no serious cries for help, urgency to the situation. Caching layer on something, even if the server operator has a switch to enable/disable it. Some emergency new log on the API calls to get performance data gathered on what is slow and propose specific fixes for calls.

Lemmy.ml is throwing errors constantly for me in casual reading and commenting. Spent 30 minutes reading and looking at new incoming comments and posts on lemm.ee - it seems sluggish to me, more data than my test server - and routine listing of pages seems slow.
