Performance of what code was 30 times less? It would make a great project for someone to investigate in depth why Rust performs particularly poorly (or why Java performs particularly well) in a specific area - if only you could provide the necessary details...
Yeah I wanted to. I reached out to my Rust devs and everybody said that my code is perfectly fine. It means I have to dig into the library code but does not have enough knowledge about Rust performance and what tooling I am supposed to do or what are the knobs that I need to adjust for higher performance.
