mCaptcha uses a proof-of-work(PoW) mechanism to rate limit users or potential bots. In order for this to be effective, the PoW should be configured properly.

This creates an unfair advantage for crackers using these bots over legitimate users, who usually use browsers to access a website.

So I wrote these to compare native and WASM performances:

The tests were run on my development machine featuring an Intel Core -i7-9750h.
