@jerry please do keep us updated on which changes improved performance, if at all. Will be very helpful for other instance admins.
@jerry oh, that document! I read that one too because beam.smp
on my single-user instance was continuously consuming ~50% CPU (I have a 2-core Hetzner VPS). Thankfully the problem went away on its own and hasn’t returned.
RE slugginshness: I’ll keep using Akkoma, but it does seem to have random performance issues — another single-user instance admin I know has BEAM consuming 6.6 gigs of RAM
