Re:Sub-10 ms Latency in Java: Concurrent GC with Green Threads

True! It's not trivial to get 10 us latency even in C++, Rust, etc. You have to do OS-level configuration, and you can't touch network or disk.
But beyond that, the actual code you write is fairly natural for those languages. You can't allocate, and your code and data have to fit in the cache. But you can use normal language constructs, and most of the standard library - neither of which is true for Java.
