As someone working on systems that handle trillions of message per day in Java, I find this hard to relate to. Is it bad code? Some critical infrastructure flaw? Misunderstanding of memory options settings or how they work in containers? Startup time is definitely a concern. Good luck on the throughput front though. Java libs (like Netty) still outpace what's available in Rust. You may end up with your own code being more performant, but the things you rely on externally being slower. This was our experience when trialing re-writes in Rust.
