Hi there! After a few hours of reading list archives and source code I need some clarification on the current state of FreeBSD forwarding capabilities.
Given the following setup: - Quad Core CPU - Intel 82576 NIC (igb) - 8.2-RELEASE - Router with BGP full table 1) Queues: Card and driver seem to have support for multiple TX/RX queues. How many cores will it use for RX / TX per NIC? 2) Fastforwarding vs multiple netisr: In the past (6.x) using fastforwarding=1 was the best option for dedicated routers. I found "multiple netisr" added to 8.0. Can that help with routing on multiple cores? Any experience from using it in production? 3) lagg: I found lagg(4) mostly mentioned on home user setups. Any experience with using lagg in high-pps environments? (>100k pps) Will lagg play nicely together with multiple netisr routing or fastforwarding? How much overhead will it add versus a single connection? Thanks a lot Markus _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
