The Test:  iperf -P 3 -c REMOTE_ADDR Server A (ix1) -> Server C (ix0)  = 9.4Gbps Server B (ix0)-> Server C (ix0) = 5.6Gbps Server C (ix0)-> A (ix1) or B (ix0)  = 5.0Gbps The motherboards are identical between A,B and C and the configs very similar.  The only difference is that Server A is plugged into ix1 while Server B and C are using ix0. I am not modifying the flags at boot (eg ifconfig -tso), yet ix0 lacks TXCSUM,TSO4,TSO6,LRO,WOL. ix0: flags=8943 metric 0 mtu 1500 options=a538b9         ether *ac:1f:6b:6a:14:6*4         media: Ethernet autoselect (10Gbase-T ) ix1: flags=8843 metric 0 mtu 1500 options=e53fbb         ether *ac:1f:6b:6a:14:6*5         media: Ethernet autoselect (10Gbase-T ) I did try adding some flags to ix0 and -- not sure if this was the reason -- the box started acting oddly and I ended up rebooting it. My hunch has is that there is somethign with the TSO4. Rudy
