Multithread for the win

[bdelespierre]

Multithreading the algo would significantly improve the performances. We may use the pthread library when available or proc_open (if none are available well 🤷‍♂️ )

And it would be so much fun to code 🤩

Found this article about an implementation in Java (see PARALLELIZATION ANALYSIS). May be useful.

If you're considering multithreading, fibers might be an option too.

Looks amazing 🤩

This feature is available in php 8.1.
Unfortunately, 8.1 is still in beta.
According to the php team, rc2 (release candidate) will be released on "16 September 2021".

I believe we should implement several adapters for concurrency/multithreading.

I think we should start with pThread because it has the best portability and support at the moment.

Great. Let's go ahead with your plan!
