it really depends on the mono repo. A mono repo where the dependency depth is very shallow ( many projects depend on a few common projects) might not benefit very much (the projects don't need to wait for each other anyway l, just for the initial common dependency projects). Mono repos where the dependency graph is deep will benefit a lot. In such mono repos there was a limit to the amount of paralelism available.

I've been working on this for a while now, was really excited when I saw the numbers. Was expecting them to be good, but they turned out better than I hoped.
