[REQUEST]: yjit, jmalloc, Ruby3+ - experiences

[zealot128]

Recently, came across many mentioning of improved speed with YJIT and memory consumption with jmalloc.

Would be glad to listen to a (short?) talk or have a discussion about personal experiences, problems, shortcomings before/after comparison..., especially for medium and large apps.

👍 we're currently running with a malloc_trim distribution of Ruby for better heap memory releasing. But we've also come across interesting articles about jemalloc and it wouldn't be hard for us to switch to it given that gem compatibility is fine.
