Setting it up is quite simple, but it doesn't compile with gcc 3.x...
Authors of this stuff proposing to use it with FreeBSD 4.x, so it is well
tested on out favorite system:)

Yes, on website kernel patches are avaliable for tunning, but for new
releases of 4.x this isn't necessary, all could be configure with kernel
options and sysctls (for 4.8):

        options         MAXFILES=16384
        options         HZ=1000
        options         NMBCLUSTERS=32678

        kern.ipc.somaxconn=1024
        net.inet.ip.portrange.last=40000
        net.inet.tcp.delayed_ack=0
        net.inet.tcp.msl=3000

Rest is quite simple/well documented. Tests in theory could be run on
one machine, so... And some nice looking results generated by web-polygraph:

        Without any proxy:

        With squid:
        http://garage.freebsd.pl/pm3-05-11-2k2
        http://garage.freebsd.pl/pm3-06-11-2k2
        With external proxy:

PS. I'm CC-ing this thread to one of polygraph's authors, he could be
    interested as well.
