This is a bit better than the previous maxim of 750064pps / 360Mb/sec that I was able to achieve without tuning parameters with ethtool, but still not near the 1.1Mpacks/s that shoud be doable with my card?
Please check what numbers you can get using dummy0 device instead of real ethernet driver. Here : (E5540 @ 2.53GHz) clone = 1 Result: OK: 34775941(c34775225+d716) nsec, 100000000 (60byte,0frags) 2875551pps 1380Mb/sec (1380264480bps) errors: 0
