Comment 3 for bug 402114

Note that I also think the fragmentation issue is affecting regular fetch. As my 'size-on-disk' after running 'bzr pack' is 106MB of .pack files. But the largest .pack in the launchpad repo is 160MB, which is already 60% too large.

Now, doing 'bzr branch' with a loosely packed repository will generate a new repository that has a single .pack file, but has the *same size* as the loosely packed repo. Which means that we won't notice that we really do need to repack this repo, because while the groups themselves are too loose, they are all sitting in a single .pack file.
