You're not the first fedidev to experience this, Lemmy is just extra :

You may have noticed pixelfed.social is slower than usual, after some investigation, I have discovered that Lemmy is behind the sudden surge in traffic. While we are implementing Groups, we expected additional load from Lemmy and other Group supported projects However, I never anticipated how much activity we'd get from Lemmy To put this in perspective, lemmy.world has sent more activities to us than mastodon.social (to pixelfed.social) I'm overhauling the inbox again to better handle this!

Mastodon (mastodon.social)
