Ok, so since people are talking about it, and i've been knee deep in at least the older intel gige interrupt moderation - at maximum pps, how exactly is the interrupt moderation giving you a livelock scenario?
The biggest benefit I found when doing some forwarding work a few years ago was to write a little daemon that actually sat there and watched the interrupt rates and packet drop rates per-interface - and then tuned the interrupt moderation parameters to suit. So at the highest pps rates I wasn't swamped with interrupts. I think polling here is hiding some poor choices in driver design and network stack design.. adrian _______________________________________________ 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"
