how tso (tcp segmentation offload) effect TCP bidirectional test sending throughput.

[Varun Sharma <vsdssd@xxxxxxxxx>]

Hi,

if we off tso (tcp segmentation offload) on sending side ,  TCP Bidirectional test sending throughput decrease as compare to TCP Unidirectional test sending throughput .

whereas if we on tso(tcp segmentation offload) on sending side , both test give almost same sending throughput result.

is anyone know how tso(tcp segmentation offload) effect TCP Bidirectional sending throughput ?

i am using iperf-2.0.5 for this case.

Thanks in advance.

Regards

varun
