8–Linux Driver Installation and Configuration Linux Performance Tuning

Here is an example of iperf from the server side:

% iperf -s -w lM -1 16k

Here is an example of iperf from the client side:

%iperf -c <ipAddr of Server> -w 1M -P12 -l 16k -P<number of threads>

Optimization

Note the following:

PCIe x8 provides optimal performance for 10GbE.

MSI and MSI-X interrupts perform better than legacy interrupts.

Linux kernel version 2.6.15 and higher provide better performance optimization.

Check CPU utilization on the host for CPU-bound bottlenecks.
