I am using iperf v 2.0.5 for testing 10G card. Its a dual port card.
Two 16 core machines with 64GB RAM are connected back to back.
In
TCP Bidirectional test case sending throughput decrease as compare to
TCP Unidirectional test case sending .
All cases use default setting . No extra parameter is set.
In case of 4 Client threads Output comes :--
Unidirectional Send Process --- 9.6 Gbps
Bidirectional Send Process ---- 4.9 Gbps
In case of 8 Client threads Output comes :--
Unidirectional Send Process ---
9.7 Gbps
Bidirectional Send Process --
6.4 Gbps
In case of 16 Client threads Output comes :--
Unidirectional Send Process ---
9.7 Gbps
Bidirectional Send Process --
