What's interesting is that Git is fast up until it isn't, and it's written in such a way that fixing performance issues that do pop up is hard (or extend the software when more custom behavior is needed).

That's why Facebook chose to just fix the slow parts of hg[1], rather than fix the slow parts of git, to build a VCS which would scale with its codebase.

On the other hand, Google seems to successfully use Git in the same way.

Google does not use Git for its monorepo.

Afaik Googlers can use git client-side. The central repo is certainly not git though.

Also parts of Google, like Chrome, Android, and Go, do use git.

Or Microsoft (Windows is using Git).

With extensions to make it bearable for their code size.

Just as Facebook does for Hg: https://bitbucket.org/facebook/hg-experimental

Microsoft wrote a new filesystem driver for git because extending the code itself was too difficult...

They also worked a lot on Git itself.
