I know when I was running networking tests I found a huge dip when
writing 4k packets. NetBSD would do something totally stupid and
send lots of little packets rather than 4 1024 byte packets or 2 1500
and one 1096 byte packet. I think it would actually send a series of
256 byte packets.
This made for a huge performance hit.
