Lemmy starts out pretty chill, but the longer it is running, the more CPU it’s using. Until I restart it again, and then the process starts over again. It’s just /app/lemmy that’s eating the cpu cycles. Looks like there are some threads that keep requeueing themselves, until eventually that’s all it’s doing.

Does anybody have any clues or pointers about this?

I’m running 0.17.4, haven’t made the jump yet to 0.18.

Mostly receiving posts and sending out to federated servers.

On my instance, i have a lot of federation incoming messages, subscribed to every large community I could find. And I’m getting posts, comments, votes coming in constantly and the CPU usage for lemmy_server is pretty high/constant. The digital signature and boilerplate federation text is actually high overhead for a single upvote to be processed, etc.

But CPU usage goes go down if there are no messages for a minute, but 20+ servers sending to my server constantly, it isn’t idle for long.
