I can offer you this:


model      packets/sec



2851       11 KPps     23.8 Mbps      79% CPU

2821        6 KPps     13.6 Mbps      53% CPU

2811        3 KPps      8.0 Mbps      80% CPU

2801      2.6 KPps      5.8 Mbps      83% CPU

1841      2.5 KPps      5.7 Mbps      79% CPU

2691      5.1 KPps     11.4 Mbps      81% CPU

2651XM    1.3 KPps      3.0 Mbps      85% CPU
