@anarchistbicycleclub consider tweaking the settings in config/sidekiq.yml -- the number of queues for "push", the concurrency, and also the stuff in mastodon-sidekiq-push.service (DB_POOL and the "bundle exec sidekiq -c 10 -q push`, tweaking those values). I am not an expert in this stuff I just try different numbers and google to make sure I'm not being a total idiot
