@james Thanks! How’s it been running ruby.social? Is mastodon still using puma?

@james Nice!Post-RC going well, one fewer background priority. Work (HashiCorp) is busy but not too busy, kids (11 and 7) doing great.

Doing research on type checking systems in dynamic langs and love to hear folks opinions of RBS, mypy, typescript and other such systems. What’s annoying? What’s helpful?

If folks neee help scaling mastodons, as the primary puma author I’m happy to help! A quick rule of thumb is using workers (-w) increases parallel requests at the cost of RAM, and threads (-t) increase concurrency. If it’s struggling, I usually tell folks to just add one more worker and see what happens.

@seb @nova Would you mind sharing your puma settings? Trying to put together a tuning guide and wanna try help folks correlate active users with cpu/mem/settings. Thanks!

@seb @nova 1 worker and 20 threads? So WEB_CONCURRENCY=1 and MAX_THREADS=20?

@seb @nova Ah! So that’s 8 processes, each running 20 threads.

@seb @nova One more quick question: how many users does your instance have? (I dunno if mastodon has this metric, but active users would be useful too I think?)

@james @baweaver bigger than RailsConf! Most there was a shade under 2k.

To all mastodon admins:Hi! I’m Evan Phoenix, the primary author of puma, the ruby webserver that powers mastodon!Please reply or DM me if you need tuning help! I’ve got no officiation with the mastodon, just want to see you succeed!(Quick Tip: set WEB_CONCURRENCY to core count * 1.5 and then tune MAX_THREADS. High thread values will see diminishing returns!)

@getajobmike For sure! Setting WEB_CONCURRENCY to cores * 1.5 can result in puma soaking up 100% of the cpu. So if you're running sidekiq on the same cores, use 1 * cores or even 0.8 * cores is prudent.

@nealr @ruud now that's some growth! How's it holding up? How much hardware are you using (cpu cores, memory)?

@jolvera So the official tips don't give concrete suggestions about how to tune puma. So it's still correct, just not specific enough!

@jolvera Yeah, probably! I want to figure out a way to gather some usage data from installations to provide even better info as well.Also considering releasing a special puma-mastodon gem that will tweak these settings automatically.
