Based on my past experience, it was a major source of routing performance dependency on traffic patterns (it's basically flow-based forwarding). Anyway, with very few flows, we get quite decent performance (several hundred megabits five-minute peak, and we haven't bothered tuning yet), running on mid-range single-socket server boards and Intel NICs (PCI-X, this is all 2006 hardware). We use a router-on-a-stick configuration with VLAN separation between all hosts to get a decent number of ports. My concern with PC routing (in the WAN area) is a lack of WAN NICs with properly maintained kernel drivers. -- Florian Weimer <[email protected]> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99
