The following message was posted to the FreeBSD net mailing list:

With a link to the following paper on the subject:

Page 11 mentions two different projects that both reached 1 million pps 
throughput using IP FastForwarding.  These were mentiond in a mailing 
list thread on the FreeBSD lists, although I have not yet bothered to 
track down the exact threads.

This presentation was made by Andre Oppermann on Sept. 2, 2004 at the 
SUCON '04 conference.  http://www.suug.ch/sucon/04/

I didn't notice the "it's dead" message until after I had responded.  My 
fetchmail setup was b0rked on the weekend and I was wading through ~600 
messages, replying as I went, instead of reading through the whole 

I'll let it die, now, though.  Just thought I'd post the links for 
others to read / research.
