@mikey @m @aral Yep, Aral has a lot of followers and also is following a large number of people.
His plan has a limit of 12 Sidekiq threads. So, no matter the tuning, only 12 concurrent jobs can be active at the same time and with the large numbers of followers/following/activity more threads would be best but that would make the cost of hosting for a single user instance hosting even more expensive.
