I found Java's to be quicker than Rust:

Java:

    time java Test
    117777800
            0.60 real         0.52 user         0.12 sys

Rust:

    time ./test
    117777800
            1.94 real         1.89 user         0.00 sys

What flags did you use with Rust?

Both `-O` and `-C opt-level=3`. I'm guessing this is one of those high throughput scenarios where having a GC is quicker because it's able to defer deallocation until the end of the program.

-O is opt level 2, incidentally.

Yeah, I think you’re right. Very interesting!
