        guile --version?
EDIT: Guile3 brings JIT support...

Guile always compiles code before running it, but adding a JIT it's only from v > 2.91.x, and by default at v3.

Ah. This is on Guile 2.2, apparently. Installing guile3 and rerunning...

Better, but still slower by about 1.5x.

    $  time guile3 fib.scm
    guile3 fib.scm  2.01s user 0.02s system 99% cpu 2.047 total
edit: apparently my cpu was still being throttled post-build or something, as the initial runs were around 3s. Rerunning slightly later, it was noticeably faster.

Well, not bad considering Guile3 and it's JIT are pretty early on release compared to the enormous work from a company as huge as Google with a full team working on v8 across years.

Guile3 will improve that, too.
