My arrogance pushes me to ask, why not? I strongly believe that by 2.4 the
sockets stuff should be polished enough to at least match *some* of
Apache's benchmarks at least on Linux.

Don't forget that once the server "accepts" a connection it passes it down
the line to be processed "with message..." which in theory means it is
ready to accept another one right away. Another mechanism servers use for
administering large numbers of calls is KeepAlive which basically limits
the number of requests per connection and also times out if no requests
were received from that connection.
I didn't try it but it might be possible to open several instances of the
server to satisfy high demand, if needed - on Linux again.
