For random src/dst ports and IPs and on the chelsio t5 40gig hardware, I was getting what, uhm, 40mil tx pps and around 25ish mil rx pps? The chelsio rx path really wants to be coalescing rx buffers, which the netmap API currently doesn't support. I've no idea if luigi has plans to add that. So, it has the hilarious side effect of "adding more RX queues" translates to "drops in RX performance." :( Thanks, -a On 23 January 2016 at 01:31, Pavel Odintsov <pavel.odintsov@gmail.com> wrote: > Hi! > > Great job!
