OTOH, the loop at:

#68

runs about 7x faster with nectar than node.

Other test code at e.g.:

time node fib.js

real 0m40.203s
user 0m40.191s
sys 0m0.012s

nectar fib.js -o fibnectar

it should not be so slow, quite strange

Problem persists even after reinstalling a fresh Debian 12.

Likely specific to the OS or a particular version of the OS or some packages?

Any other OSes to try?

OTOH, since Node seems to work flawlessly, then maybe it's just nectar?

There's no difference when building with:

node nectar fib.js -o fibnectarman
