A good starting point would be:
http://www.netbsd.org/guide/en/chap-tuning.html

Other links that may be of interest:
http://proj.sunet.se/E2E/tcptune.html
http://www.psc.edu/networking/projects/tcptune/#NetBSD

You should also tcpdump your traffic when the problem occurs
to be actually able to see what happens.
