    And just as a data point, I've used that patch for some WAN connected
    machines. It worked very well (order of magnitude increase) and we have
    not noticed any reduction in performance on the LAN connections. It may
    be slower, but without testing I can't really tell.

    I haven't even bothered to examine if we're normally network or CPU
    bound or what, but since no one's noticed a problem, we just leave it in
    on all the machines now...

    Using -z none instead of the default ciphers gave only a small
    performance increase, so no one pressed to have it enabled. :-)
