DPDK and energy efficiency

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.
