Here are a few comparisons (13" MBP, YMMV).

  $ ./hyperfine './hello.gonative' --warmup 10
  Benchmark #1: ./hello.gonative
    Time (mean ± σ):       3.3 ms ±   0.9 ms   [User: 1.2 ms, 
      System: 1.2 ms]
    Range (min … max):     2.4 ms …  14.2 ms   455 runs

  $ ./hyperfine './hello.dartnative' --warmup 10
  Benchmark #1: ./hello.dartnative
    Time (mean ± σ):       8.2 ms ±   0.4 ms   [User: 3.9 ms, 
      System: 3.6 ms]
    Range (min … max):     7.5 ms …  10.2 ms   243 runs

  $ hyperfine 'java HelloWorld' --warmup 10
  Benchmark #1: java HelloWorld
    Time (mean ± σ):      90.7 ms ±   1.3 ms   [User: 83.2 ms, 
      System: 23.9 ms]
    Range (min … max):    88.7 ms …  94.2 ms   31 runs

Which JDK? OpenJDK 14 on my machine:

    ~> Measure-Command { java Main }
    Milliseconds      : 59

I got:

OpenJDK 8: ~80-90 ms

OpenJDK 11: ~60 ms

OpenJDK 14: ~50-55 ms

The first runs were a bit slower, perhaps because the files needed by the JVM weren't in disk cache or something.

Other languages/runtimes:

Python 2.7: 20-25 ms

Python 3.8: 30-40 ms

Native binary compiled from C: 1-3 ms (so bordering on unmeasurable at millisecond resolution)

This was on Linux, and an entirely unrigorous experiment.

Nice! I'm glad startup time is getting closer to python. FWIW GraalVM native image was 16ms for me on Windows.

Also with GraalVM Native:

   ~> .\native-image.cmd --static Main Main
   ~> Measure-Command { ./Main }
   Milliseconds      : 16
