Hm. I just tested locally, and these are the times I see:

So 10 seconds to branch, 4 to commit, and 19 to push to launchpad trees. So I
wonder what is different at your end to make it slow.

Of course, for 6.0 trees it is important to use the --stacked-on option, but
since you were the one I learned that from that is unlikely to be your
problem.

No idea, sorry...
