I've seen the gains in Java; the main things that would close the gap are not yet there in Java. .NET code, especially when tuned, still has significantly more knobs in your code to tune and make faster. An example would be proper generics with value types together means less boxing in generic code in general overall but there's a lot more I can think of. I've seen almost 50% of gains, particuarly when doing math like code, of moving away from Java to .NET especially if the jump to C/C++/Rust is too much for the team in question due to other requirements.
