With centralized solutions, like Perforce, Mercurial, etc...
I think you're incorrectly putting mercurial and perforce in the same bucket. Mercurial is a lot more like Git than perforce in that it's a DVCS. Facebook made it scale by using a lot of centralized caching, but most operations (diff, looking through history, branching, etc) can be done locally.
