> It's fast enough for Stripe's API... Stripe is moving to Java.

  Every large enough organisation eventually moves to Java (or C++, or Rust). When you have more bodies than things to do you just optimize... But how did all these startups get so big?

  If you need maximum requests per second for sufficiently high volumes of traffic - ie, Stripe/Twitter/FB/whatever stuff - then yeah Ruby/Python/etc doesn't cut it. If your needs get extreme enough (high frequency trading?) then Java doesn't cut it either. Most (I suspect > 99%) use cases don't fit these criteria. I know this is skewed a perception is skewed a little by the HN crowd, where many folks legitimately are trying to build the next Stripe or Twitter, but I think the world of modern software development is somewhat poisoned by this belief that we all need to follow FAANG-scale practices and architectures.

    Java is used in HFT, and for the variant where it is not fast enough, general purpose CPUs are not fast enough so not even hand-written assembly can compete anymore. They use FPGAs for that kind.

      Java is used in HFT for markets that have a time window, but only because they tune the GC to never kick in during market hours
