When I saw the bar looking like the Burj Khalifa, I assumed it was
.world
instead of.ml
. Interesting.Props to [email protected] for dealing admirably with the Rexxit hug of death.
I’m expecting that JSON parsing is a huge overhead with the fediverse. I work on a SAAS that needs to do all its internal processing in under 10 ms, and serializing/deserializing ends up being a sizable chunk of server time. I saw a 40% reduction in runtime using simdjson for deserializing, and there exists a rust crate for it, but I haven’t had time to look the Lemmy code over.
Can anyone with an overloaded instance get on their command line and gather a decent flamegraph so the performance folks can aim optimizations in the right direction?

Yep, it seems completely different to when I last looked.
