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?
I’m pretty sure it’s the first flash advertising campaign I’ve seen on Lemmy. Baked beans are a traditional Fourth of July food, so it’s a nice reminder for a million people to bring some beans to their cookout tomorrow.
