Looking at the snapshot, it seems that the git support access IO for a bunch of folders through FileStatusCache.containsFiles()->FileStatusCache.getStatus() - this should be eliminated, the folders are not interesting in the scope of containsFiles and listFiles(), git does not track folders.
So calling getInfo() instead of getStatus() should be sufficient, information about files should be stored in cache anyway, so there's no need to involve isIgnored logic and sharability query.
