Hi! The test configuration has MTU size = 1500.
I'm using MTU=1492, because of IBM recommendation, for eg. in redbook lx26apr04dd01: "For OSA-Express CHPID in QDIO mode devices with the Ethernet feature, the recommended MTU size is 1492 (8992 for jumbo frames). Chosing 1500 (or 9000 for jumbo frames) can cause performance degradation." What is the connection between SO_SNDBUF=14596 SO_RCVBUF=14596 parameteres and the MTU size?
