GVFS 是解決微軟內部自己在用 Git 的痛處，因為微軟的 repository 都... 有... 點... 肥... (畢竟有不少產品發展了很久)。
目前 Git 的操作是卡在 I/O 與 memory cache 的限制上：
Also, Git wasn't designed for a codebase that was so large, either in terms of the number of files and version history for each file, or in terms of sheer size, coming in at more than 300GB. When using standard Git, working with the source repository was unacceptably slow. Common operations (such as checking which files have been modified) would take multiple minutes.
GVFS 的想法是有用到的部份再真的去拉，藉此大幅減少 I/O 需求...
