Heh. Except you need the fancy tool pv(1).

Except tcpdump defaults to 68 bytes of packet headers: tcpdump: listening on bge0, link-type EN10MB (Ethernet), capture size 68 bytes... You could dump to a file for a minute and do some calculations. Any way to have tcpdump only dump the payload without the headers to calculate actual file transfer rate?

-s 0 will output the full packet
