Mercurial scaled better actually. It's 1 of the reasons Sun, Mozilla, and Facebook used it instead of Git. Typically Git was a bit faster for most operations on Linux. Mercurial was a bit faster for other operations. Especially on Windows. And both were much faster than the rest. Bitbucket and GitHub started around the same time. GitHub just executed better.
