Everything you say is true, but it is highly unlikely that CPU core performance has much to do with Windows "fork" emulation performance. Executing tests in parallel would help some but quite likely not nearly as much as hoped for.

A more proper solution is to eliminate the forking almost entirely with a better shell design. This would improve Unix execution performance too.
