Just realized maybe some instance admins haven't seen this page, but I *did* describe how exactly Mastodon can be tuned: https://github.com/tootsuite/mastodon/blob/master/docs/Running-Mastodon/Tuning.md

@Gargron I found that really useful, though I'd love it if someone could add more detail for new admins with little context. I had to experiment a bit to get everything right, and lean on programming knowledge to make educated guesses at more-workers v more-threads-per-worker -- not all admins have that.

I considered a PR, but I'm still guessing/experimenting so I'd like to see a more experienced Masto admin write it.
