You could do a lightweight checkout that would not need all the history 
or you could create a stacked branch. Both of these should significantly 
reduce the bandwidth and download time. If the smart server was running 
on the Python site I believe it basically does the whole tarball thing 
for you without any change in commands you execute.

 From a benchmarking point of view it would also make sense to benchmark 
smart server against smart server. If Bazaar is just using a dumb file 
storage then it does not make sense to compare the performance of that 
to git, say, which can only use a smart server AFAIK.
