    Great response.  Again, highlights the need to have some
    standard way for benchmarking this sort of stuff.  Would
    be a good use of Snakebite; everything is on a gigabit
    switch on the same subnet, multiple boxes could simulate
    client load against each server being benchmarked.

    (I don't think my idea would really start to show gains
     until you're dealing with tens of thousands of connections
     and 1Gb/10Gb Ethernet traffic, to be honest.  So, as I
     mentioned in a previous e-mail, it depends on what our
     goals are for the next-gen AIO framework (performance
     at whatever the cost vs not).)
