I think at this point it is clear those who care about memory usage and deterministic performance will use C/C++/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'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/OpenJDK GC. Working in Java for 10 years make me realize that so many solutions Java/ JVM ecosystem provides are to the problems that Java ecosystem created in first place.
