my mastodon server's been really struggling with running all these git polls & discussions -- there's a lot of federation to do, and when I made a new post it would take up to 45 minutes for that post to actually get sent to anyone because the server had to chew through 20,000 federation events
so I upgraded to the $89/month masto.host tier to see if that helps
(not looking for advice, just sharing what it's like to run big discussions on mastodon. masto.host has been great.)
