I'm using R610's R620/R720's and I have 2 tests I try. The first is iperf with localhost and the server and client. I'll get ~2Gbps on the 610's and ~1.5gbps on the newer servers. WebI'm currently using dumb switches. I can readily reproduce the packet loss issue running iperf to generate multicast traffic. If I ping my board with the ksz9567 from a PC while iperf is generating multicast packets, I get tons of packet loss. If I run heavily loaded iperf tests that are not multicast I don't notice the packet loss problem.
