Why only half? I have pulled FreeBSD ISOs via torrent and it was
stunning to see the performance.

The system I was loading it to had (at the time) only a fastE (100Mbps),
but it loaded at a steady 90+ Mbps and spent a lot of time above
95M. Now that I am connected from that system at 1000M, I should see how
it does.
