I agree that test-pmd iofwd is a good reference to track regressions or analyze performance issues, but I'm not sure it's a real use-case. To me, it's more important to ensure that l3fwd performance stay stable compared to iofwd. I think l3fwd is the most representative of a DPDK application. Other use-case could include: - virtualization, maybe using ovdk? - ip fragmentation / reassembly - an application that encapsulate or decapsulate in a tunnel Regards, Olivier
