Comment 3 for bug 608702

I've done an lsprof, and it seems to not be the has_version() check that I thought it was.

Looking at the profile, it appears to be 16 'BranchStore.get_branch' calls, which have 16 associated get_branch_parts calls which then spends 62% of the time in Branch.open() and 38% of the time in _branch_location.

both of those times seem surprisingly slow given that it should be re-using the bzr connection, and the profile is running on Jubany, which should have very low latency to the codehosting machine.
