Haven't checked graalvm in a long time. So, I got graalvm-jdk-25.0.1+8.1 for x86_64. It's a lot faster than Julia, and maybe 43ms is not slow in "human terms", but it's still pretty slow compared to some other competition. This was for a helloworld.jar [1]. On my laptop (i7-1370P, p-cores) using tim[2]:

    $ tim "awk '{}'</n" 'tcc -run /tmp/true.c' 'perl</n' 'py2</n' 'py3</n' 'java -jar helloworld.jar>/n'
    97.5 +- 1.5 μs  (AlreadySubtracted)static dash Overhead
    94.9 +- 3.2 μs  awk '{}'</n
    376.7 +- 4.6 μs tcc -run /tmp/true.c
    525.3 +- 2.7 μs perl</n
    3627.7 +- 6.0 μs        py2</n
    6803 +- 11 μs   py3</n
    42809 +- 71 μs  java -jar helloworld.jar>/n

Also, probably there is some way to tune this, but it used over 128 MiB of RSS.
