Yes, I'm > half serious. 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. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
