rayon test

Testing this PR, that allows us to run rayon on Wasm without threads: rayon-rs/rayon#1019

We benchmark summing a Vec<u64> with a for-loop, with iter().sum() and with par_iter().sum().

Results

I wanted to see wether or not using par_iter() without any actual threading would add a lot of overhead.

Tested on an M1 MacBook Pro.

Native

We see par_iter winning, as expected:

Wasm in Firefox

We see that iter() and par_iter() performs almost exactly the same, with a very minimal overhead cost for par_iter():

Running it yourself

Natively

cargo run --release
