My experience > is that you definitely want to run "bzr pack" quite often. I know the pattern now. The emacs bzr repo gets quite much slower after every "bzr pull" update. My second test (the rerun) in bzr-packed repository gave 1 minute 15 seconds for whole-history "bzr log". Since then I have bzr-pulled three times (20 new commits in total) and I get 1 minute 45 seconds for "bzr log" now. Just a couple of pulls more without packing the repo and we'd be back in the situation of my first benchmarks (i.e. "bzr log" taking three minutes).
