This appendix demonstrates how to achieve very low latency coupled with minimum jitter on a system fitted with an X2 series network adapter and using the OpenOnload kernel-bypass network acceleration middleware. These techniques also apply to other supported network adapters that use the sfc network driver, such as 8000 series adapters.

The procedure will focus on the performance of the network adapter for TCP and UDP applications running on Linux, using the AMD supplied open source sfnettest network benchmark test tools, and also the industry-standard Netperf network benchmark application.

The results of these tests can be found in Latency Test Results, and Latency against Payload.

Note: Please read the supplied ONLOAD_LICENSE file regarding the disclosure of performance test results.
