It was ~10 million packets per second with 500 bytes packet size, if I remember correctly. The speed is highly depending on packet size. Actually packets per second is actually a better unit than (k/m/g)bits per second. I mostly care about the 500 bytes packet size values in benchmarks because this is what I think is a good approximate for the average size in most networks. However, the 64 byte packet size values might also be interesting when dealing with "weird" applications or DoS attacks. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
