Application for rte_flow performance testing. The application provide the ability to test insertion rate of specific rte_flow rule, by stressing it to the NIC, and calculate the insertion rate.
The application offers some options in the command line, to configure which rule to apply.
After that the application will start producing rules with same pattern but increasing the outer IP source address by 1 each time, thus it will give different flow each time, and all other items will have open masks.
The current version has limitations which can be removed in future:
The application also provide the ability to measure rte flow deletion rate, in addition to memory consumption before and after the flows creation.
The app supports single and multi core performance measurements.
The test-flow-perf application is compiled as part of the main compilation of the DPDK libraries and tools.
Refer to the DPDK Getting Started Guides for details.
Please refer to EAL parameters (Linux) or EAL parameters (FreeBSD) for a list of available EAL command-line options.
The following are the command-line options for the flow performance application. They must be separated from the EAL options, shown in the previous section, with a -- separator:
sudo ./dpdk-test-flow_perf -n 4 -w 08:00.0 -- --ingress --ether --ipv4 --queue --flows-count=1000000
The command line options are:
