Java has been broadly used in HPC and low-latency trading software for years now. That's not only because much more attractive time-to-market but also because in many cases Java is on par with c/cpp when it comes to performance. Sometimes even better. I'm under the impression that you are not interested in educating yourself on the topic, however if I'm mistaken, have a look at some reasons why Java can be as fast or faster than c/cpp: - TLAB (thread-local allocation buffer) - Escape analysis - Mono- and bi-morphic callsite optimizations - JIT in general (dead code elimination, implicit null checks, CHA-based optimizations, etc). Also, you don't have to use Oracle JVMs. There's IBM's J9, OpenJDK-based Zulu, or commercial JVM from Azul (Zing).
