I have to admit that I learned a lot of these things fairly recently. The large repository stuff has been added into core piece by piece by Microsoft and GitHub over the last few years, it's hard to actually find one place that describes everything they've done. Hope it's helpful.
I've also had some fun conversations with the Mercurial guys about this. They've recently started writing some Hg internals in Rust and are getting some amazing speed improvements.
I'm also thinking of doing a third edition of Pro Git, so if there are other things like this that you have learned about Git the hard way, or just want to know, let me know so I can try to include it.
