No, this just isn't true. Git walks the DAG, sure, but it typically only
ever needs to look at one or two parents for most operations.
I've said before, I think, that "git gc" might be the way to go if you think
things are slow, but what are you doing where things are slowing for you?
If you're not as you're thinking subtrees is somehow going to make things
faster because it's completely self-contained to one or two directories,
that's also sadly mistaken.
