[OpenIndiana-discuss] Ethernet transmit traffic distribution

[Santosh R]

Hi,
 While running multiple iperf threds , mpstat shows some of the CPUs fully
saturated (doing xmit) resulting in lower throughput.
How (some control setting?) to distribute this Tx traffic across all the
CPUs? I am using oi_151a8.

Here is the mpstat output.
