Hi, Well, hm. What's generating the interrupts? How many interrupts/second are you talking about here?
People have asked about a NAPI style solution for FreeBSD for a while, but for most folk that are using one physical interface that does interrupt moderation/rate-limiting, it turns out to not be all that big a benefit. For boxes that haves multiple interfaces, or for VMs whose software interrupt path doesn't implement any kind of thresholds for interrupt moderation, it still can be a benefit. So maybe try looking at making your driver support POLLING and see what happens. Maybe virtualisation will be the straw that breaks the NAPI back for FreeBSD. ;) -a _______________________________________________ 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"
