I just reran the script a few times, and I neder got 2.x seconds again on a 
local clone using a shared repository with hardlinks, so I replaced it with a 
more realistic measure from one of the later tests: 

time bzr branch python-bzr-trunk python-bzr-trunk2 --hardlink
No handlers could be found for logger "bzr"

real    0m4.546s
user    0m3.682s
sys     0m0.737s


This definitely shows the danger of unscientific tests: You don't know how 
unsure the results are - the difference in this case was about 50%, teh 
variance is yet to be determined. 

Best wishes,
