Your benchmark script and the colored output is so cool.

That was a bit surprising to me.  Could it really be spending so much
time reading and writing revision texts that it more than doubles the
time to copy the whole repository?

I'd suspect it was using an inter-format fetch, except that you did
say you'd done the conversion first.
