In some traces I did for my PhD work about three years ago, I found that
51% of the packets were 40 or 41 bytes long (i.e. mostly TCP acks or
one-byte TCP payloads). Only 15% of the packets were maximum-sized. The
average packet size was 273 bytes. This workload was probably heavier on
telnet than today's networks; however even when doing bulk file transfer,
one packet in three is still an ack.
