Well, having actual hardware do the packet forwarding, and only having each machine process each packet once probably helps... > rcu stuff makes me nervous, what happens if that nat stuff is disabled > entirely. > > What if you made q.len and sparse/bullk flow counts atomic ops? The whole qdisc dequeue op is running while holding a global lock. The freezes I'm seeing are happening because the other cores get stuck waiting for the cake dequeue operation to complete (and thus release the qdisc lock). Which is why I suspect an infinite loop somewhere... > I tend to lean towards an overflow post 40gbit also. An overflow of what? 40 Gbps is 5 GBps, which is the unit that rates are being measured in. So there's no obvious reason to expect that... Which is not to say it couldn't happen, of course... -Toke _______________________________________________ Cake mailing list [email protected] https://lists.bufferbloat.net/listinfo/cake
