The high CPU issue that is causing midwest.social to slow way down and timeout on HTTP requests is still a mystery to me. But, it seems to do it less often and for less time now.
Here is CPU usage over 24 hours:
It's a bunch of SELECT statements in Postgres that all seem to fire at one time and take a while to complete as a batch. I've inspected the logs and haven't seen anything unusual. Just stuff federating and posts receiving upvotes.
I've been having timeout and 404 issues since I created my account last week. Typically can't browse more than 5 minutes before I start getting timeouts, which can last for several minutes to several hours before anything loads again. Thought it was a gerboa issue at first, but I'm using a browser now and getting them too.
