   Wcarchive is connected via ethernet to a 45Mb T3. It pushes an average of
700K bytes/sec during the daytime and about 250K/sec at night - or about 30G
bytes/day. It's by far the busiest anonymous FTP server on the Internet. The
above indicates that FreeBSD is approximately 1/3rd of the total traffic from
wcarchive.
