I am not sure that I understand you correctly. Are you really claiming that lack of speed is why Mercurial did not get traction, and an argument in favor of Jujutsu/jj getting traction?
Well I did not answer your second part of the question, only the first part of comparing Mercurial vs Git.
Now to the second part: I think speed still plays a role back when Bitbucket and Google Code provides Mercurial hosting and people were comparing Mercurial with Git. Eventually GitHub won the competition, so then we kinda stuck with Git.
