You're talking 10 GiGE wire speed, right?
That's more than 100 M requests/second!
If I recall correctly, the maximum number of minimim sized frames per
second for 10GbE is something like 14.7M or 14.8M each way. I think
Ooops, I managed to skip the bits-to-bytes step.:-(
Anyway, the CPU cycles needed for wire speed is obviously easy to get
then, the bottlenecks should be in the NIC/bus/hw parts.
Luigi Rizzo has gotten 10+ Mpps with an Intel NIC (just basic
networking) using his netmap stuff.
Using a two-socket server with E5-2680s, and a non-Intel 10GbE NIC
I've seen around 2.89 M pps each way on a single port with aggregate,
concurrent, burst-mode netperf TCP_RR tests. If I use non-burst mode
and many more concurrent netperf's it is more like 2.5 (from memory).
I suspect it becomes more of a context-switching benchmark at that
point. Haven't quite gotten around to driving both ports at once.
Right.
