It appears that I put my foot in my mouth.  I have read several claims
that the Vyatta software is scalable to 10G, most notably here:
http://www.networkworld.com/news/2008/031708-vyatta-open-source-router.html.
 Upon further investigation, I have been unable to substantiate that
claim.

My experience is similar to those who have posted here, pps is the
limiting factor - usually somewhere between 500-800K.  Apparently I
was over eager to believe that more had been achieved.

To Ann's question on resources; I have only used Linux routers with 1G
ports but have surpassed 10G total throughput (up+ down) using various
dual proc set ups, most often Intel Xeon in Dell servers.  A gentlemen
by the name of Martin Pels wrote a good paper on the subject early
last year that can be found here:
http://docs.rodecker.nl/10-GE_Routing_on_Linux.pdf.  He hit a wall at
700K pps and was using two dual core Intel Xeon 64bit 2.33GHz CPUs and
2GB of RAM in a Dell PowerEdge 1950.
