I'm very happy to see interest in DPDK and power consumption. But IMHO, the questions do not cover the actual reality of DPDK. That característic of "100% CPU" depends on several aspects, like: - How old are the hardware on DPDK. - What type of DPDK Instructions are made(Very Dynamic as Statefull CGNAT, ou Static ACLs?) - Using or not the measurements of DPDK Input/Drop/Fowarding. - CPU Affinity done according to the demand of traffic - SR-IOV (sharing resources) on DPDK.
The way I saw, the questions induce the public to conclude that DPDK ALWAYS has 100% CPU usage, which is not true.
