We have purchased Intel X.540-T2 dual adapter boards, which have 10 Gbps throughput speed.
We are using it for loopback connection benchmark testing between two ports, when we test it using "NetPerf utility" it gives us throughput speed of 13 to 14 Gbps.
Please guide us why this is happning because our network card is for just 10 Gbps speed. Is the board designed for higher throughput in loopback connection?? What is the best method to test low latency RTT for this card??
