You are talking about perf?

People use fucking java in HFT

dont worry, our basic tools are fine with Rust, go or even c#

[MobiusHorizons]

For cli tools startup performance matters a lot, and many languages struggle on that point (eg Java) go and rust would probably be acceptable though.

Apparently not, when so many of them are written in Python and Perl.

As for Java, if the extra ms are the end of the world, one can JIT cache or AOT compile it anyway.
