With my SFP modules in hand, I retested with 16 gig ports connected. The test was done with connection tracking on and routing. I did not do a bridging test because I can’t see anyone using this router in bridging mode. To say the least I am impressed. With standard packets, I saw consistent 15.6 GBps throughput and with small packets I saw an average of 16.6 million packets per second. Nice!
With small packets all 36 cores were maxed out but with standard 1500 byte packets I saw less than 5% CPU. That too is impressive.
Here is the test setup on the bench:
