> In other words, it’s possible to write Java, from the machine level on up, for low latency. You just need to write it like C++, with memory management in mind at each stage of development. If you do that, you lose on a lot of stuff in C++ that supports that. For example, destructors/RAII make managing memory resources a lot better. Tooling like Valgrind, ASan, etc make it easier to find issues in your memory management. With Java, you don’t have those. The vast majority of Java is written with GC in mind, and when you go off the beaten path and do memory management on your own, you won’t have the language features and tools to support you, making it harder to do than in C++.
