Well, I don't have forwarding numbers, but using a modified pktgen,
we can send and receive about 800,000 packets per second on each of
4 10G NICs in our E5 test system.
Our modified pktgen is probably slower than the upstream, as it has
a bunch of rx logic in it as well...
And, for our network emulator module (like a bridge, mostly), we can
get 7-9.8Gbps bi-directional throughput, depending on some issues
due to IRQ pinning and the spread among the rx-queues, it seems.
Thanks,
Ben
