VFS for Git
Virtual file system for Git, enable Git at enterprise scale
...VFS for Git also manages Git's internal state so that it only considers the files you have accessed, instead of having to examine every file in the repository. This ensures that operations like status and checkout are as fast as possible. Git struggles to handle enterprise-scale repositories. Operations like cloning will slow to a crawl when you have millions of files in a repository, and even something as simple as getting your repository status will leave you waiting.
