Linux Performance Tuning

6-10 NE0154601-00 A

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 versions 2.6.15 or later provide better performance

optimization.

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