Run projects in parallel? #14
Description
One of the reasons that mypy_primer is generally faster than ecosystem-analyzer is that it runs ty on projects in parallel, whereas ecosystem-analyzer only runs projects one at a time. The reason why ecosystem-analyzer does this is so that it can get accurate timing reports, but these timing reports are still somewhat noisy and unreliable -- you generally only want to take notice of them if they report very significant changes on a project. It might be interesting to see how much noisier it really makes the timing reports if projects are run in parallel.
