Hi Eddie,
Did anyone, concerning this, had a problem with the normal forwarding througput
of Click 1.4.1 without optimizing ?
I ask this question because, with an AMD Athlon XP with 2 NIC's Intel Ethernet
Pro 100 Mbps (eepro100 standard driver)(one in, other out), and packets of 64
byte, and a simple config (PollDevice -Queue - ToDevice)(both polling), I have
already packet-loss at +/- 65 Mbps load (+/- 100.000 packets/sec), which is much
less than your measurements, and earlier measurements here in Ghent.
Thanks in advance,
Peter
