Perf results on scaling Git on VSTS with GVFS (Brian Harry)

Vahe Minasyan

A little over a month ago, I gave an update on our progress of moving the Windows team to Git in the largest Git repo on the planet.  At the time, I described the scale of the Windows Git repo (over 3.5M files and ~4,000 engineers), the current performance results and set of improvements that were just rolling out that we called “O(modified)”.  The O(modified) improvements significantly improve performance by changing many Git commands to be time proportional to the set of files you’ve changed rather than the set you’ve checked out.
