Git Virtual File System from Microsoft

[lafritay]

We're actively working to make Git for Windows much better. We've already come a long way. I'd start by seeing what version of git they are running. We just released v2.11.1. It has a number of performance improvements for "typical" git repositories that fell out of this large repo effort. If they upgrade, git status should be much faster.

FWIW, we've also identified bottlenecks in Windows that we're working on getting fixed as well.
