Hi, If I'm getting it right, you are doing a test with 10 machines directly connected on the same LAN, using iperf to test the performance of the TCP/IP stack with your 10Gbit cards. But as far as I can see, netmap is not involved in your setup, you are not using it, aren't you? IOW , I don't understand what does that "+ Netmap" mean you our test description banner.
