I don't know. But I started testing with n=1 and an outer loop, so  
the Net::HTTP.start is repeated, and net/http is still winning (by  
more than URI parsing accounts for).

I will run some longer tests later to get more accurate data (and  
intermix doing it each way to minimise the effect of random net  
traffic fluctuations). I will use a static page as Robert suggested.
