Yeah, "git blame" can easily be several seconds without anything being wrong.
But "git commit" should be fairly instantaneous. Even over NFS.
That said, on NFS in particular, make sure you don't have
[core]
PreloadIndex = false
in your .gitconfig to disable the threaded index preloading.
But "core.preloadindex" _should_ be enabled by default in anything but
the most ancient git versions, and it can make a huge difference on
NFS because it allows the 'lstat()' calls to check that the index is
up-to-date to be done in parallel. Without that, git on NFS can be a
bit sluggish.
On local filesystems it normally doesn't make as much of a difference,
since things tend to be either cached or seek-limited.
