Am I finally done with these horrible, no good, verry bad #lemmy performance issues? I think I might be. Lemmy federation requires a lot more...everything...than does Mastodon style microblogging. People vote constantly. Posts and comments are longer. Everything has multiple images. And by default lemmy wants to cache everything all the time forever.
@fastfinge PieFed batches votes into big chunks to make federation more efficient. But it only works between PieFed instances so the full benefit will only become apparent as Lemmy fades away.
