The real figure of merit you should be looking for here
is "requests per second" -- HTTP 1.1; if you measure 1.0
requests, you actually end up measuring connection per
second, instead, which is not a real figure of merit.

BTW: There's actually a couple of ways to get the average
connections per second incredibly high -- on the order of
300,000 per second -- but they involve using techniques
that are not really useful in real life, since over a
certain level, your stall point moves to the number of
simultaneous connections you can support vs. the 2 MSL
for the TIME_WAIT.  Any number over around 30,000 CPS is
therefore a ramp-up number, and is not sustainable over
a long duration.
