Are you comparing to mercurial or git ? Which version of bzr were you using (bzr --version) ? I am using bzr.dev. > As my python skills are rather small, I can't contribute much > to help "profiling" the code. > I think giving the name of the projects (if they are open source) and the commands you were using would be enough to see an eventual problem. I don't have experience for large projects with long history (the biggest project I use bzr with is ~ 2000 files with ~ 4000 revisions), but I compared those with mercurial a few months ago, and they were comparable in speed for branch/st/ci/diff commands (log and blame were much slower, but again, if there is no history, I don't think that's what you are talking about). The major bottleneck happens with GNU Emacs repository. My projetcs are pretty small (in files and revisions) but they "lag". Xavier
