I think at this point it is clear those who care about memory usage and deterministic performance will use C&#x2F;C++&#x2F;Rust(maybe). Saying Java is not up there will bring Java supporters arguing endlessly how Java is so superior to anything else in market, how Java&#x27;s GC is state of the art. It would not matter to them how much expert level tuning it takes to make it work. Yeah and then there is Azul zing: a heavily over provisioned system on top of already over provisioned Java systems to have better GC compared to Oracle&#x2F;OpenJDK GC.<p>Working in Java for 10 years make me realize that so many solutions Java&#x2F; JVM ecosystem provides are to the problems that Java ecosystem created in first place.
