I also read that it can get slower than git on huge repositories but I don't have benchmarks. Not true. In fact, Mercurial is faster than Git on huge repositories; just ask Facebook--the entire Facebook application lives in a Mercurial mono repository, which wasn't possible without Git slowing to a crawl: https://engineering.fb.com/core-data/scaling-mercurial-at-facebook/ https://engineering.fb.com/core-data/scaling-mercurial-at-fa... Turns out it's been easier for Facebook and others to optimize Mercurial over the years due to it being 95% Python, which is easier to refactor. And because of Mercurial's extensibility, it's easier to replace or optimize different components.
