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 testgive almost same sending throughput result.

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

TSO reduces cpu usage. Your cpu might be a bottleneck with TSO off. -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
