learned so far: - 4 cores seems _enough to run_ but on this particular host it’s kind of marginal. 16GB ram seems plenty. - it’s been dropping pds websockets, and doesn’t seem to recover on its own. not sure why. - bandwidth is less than i was expecting. - +jetstream on this server is too much

- pds backfill is rough on this server, cpu pegs 100% - made worse by having jetstream on the same server trying to do a higher event rate - also interesting: jetstream just crashes when it’s relay websocket closes? fine if the supervisor auto-restarts it i guess.

- 4 shared cores on a 2017-era 2ghz epyc is not enough for a relay. could probably tune some things to get it there—seeing significant overhead from userspace networking + logging—but i def want more performance margin than this. for $5.5CAD i can get two more shared cores, or double that for 8

this provider has a very tempting “dedicated 4 cores” offering that might work but it can’t be configured with enough storage for much of a replay window. otherwise i’m looking at ~$120/mo and that gets me a whole big real dedicated *machine*. maybe if i push for some kofi/github sponsors i could.

What about the community grants? Would they help?

What parameters are you running it with?

postgres on the same host (nvme), persist dir on network storage (SAN i think?) lenient sync validation otherwise all defaults from the repo dockerfile. podman, for some reason, which is why i ended up with userspace networking (oops)

one thing I can think of is that you should probably add the bsky PDS domain to TRUSTED_DOMAINS, otherwise they get throttled. maybe I should make that the out-of-box config
