Firstly, let me say, I think it's a great OS! I will be going online full time soon, and I'll be using a FreeBSD box as my router. I have noticed some strange behaviour with packets originating from a FreeBSD box. I first saw this when connecting to an IRC server which uses FreeBSD, and just before I saw it come from my own FreeBSD box. The behaviour is this: seemingly small amounts of complete data (ie: a line on IRC) are split into two packets, and are sent about a second apart. The trace from my current router (not a FreeBSD box) shows this behaviour. Note the first packet has the PSH attribute. At most other times a complete set 500+ bytes is sent in one IP packet. One idea I had: possibly some sort of circular buffer quirk. I don't know anything about the internals of FreeBSD so this is a wild guess. Hope this helps, or you can enlighten me on this seemingly strange behaviour, if it's supposed to do that!
