Indeed - but not by default. I think comparing bzr and git history-based
timings is difficult, since git and bzr are so different in what they
consider important. Git is slower at showing history of one file
compared to the whole project, log does not follow rename by default
either. For some of the projects I am working on, git log --follow is be
several times slower than git log. But things like git blame -C -M (to
get history across files) is a wonderful thing - I miss it dearly
whenever I have to use another VCS.
