C# sure, but unless you are doing something pretty close to the core purpose of some giant java framework java is slow and verbose

  Slow and verbose compared to what?
• ntonozzi 4y ago
  Java, Go and C# (and node) have very similar performance, e.g. https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/go.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/.... For all of them, the key to writing high performance code is avoiding allocations and boxing. Go and C# both do this slightly better than Java, but in most domains where these languages are used, this is not a big difference (and this is where you might use C/C++/Rust instead). I've found Go to be more verbose than Java, but I haven't used Go much since generics were released.

  It's amazing how the "Java is slow" myth survives to this day.
  • johnny22 4y ago
    i just read "java is slow" as "java is slow to startup" and that helps. Java is slow(er) to to startup, but once it's going, it's pretty good.

      That doesn't matter if you're writing a REST api. If you're writing a CLI app, then I agree that's a problem.

        Sometimes matters, e.g. when you deploy new code.
        • oauea 4y ago
          Not really, just do a rolling deployment like you should be doing anyway. No one cares if the new version takes 1 millisecond to start up or 3 seconds because they literally won't notice.

            But 3 seconds isn't on the table. It is more like 20-30 seconds on a medium sized app and 8 seconds for a small one.

              If your Java app takes half a minute to initialise it's the app's problem, not Java. Modern Java frameworks have moved from a dynamic deployment model to statically compiled and can start in milliseconds. (for example, see the benchmarks on https://quarkus.io/blog/runtime-performance/ https://quarkus.io/blog/runtime-performance/)

            Rolling deployment is a hack imho. Adds complexity and hence yet more potential failure modes.

              Hardly, it's a fantastic guardrail when combined with health checks. You can say "you don't need it", but everyone makes mistakes sometimes. Make those mistakes not matter. You also take backups, right? Same idea.

      I meant slow to develop in.

        With features like records, pattern matching, enums, and many more, I find it much better than the likes of Python or golang.
