The way I saw, the questions induce the public to conclude that DPDK ALWAYS has 100% CPU usage, which is not true.
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.Em seg., 22 de fev. de 2021 às 04:30, Etienne-Victor Depasquale <edepa@ieee.org> escreveu:Hello folks,I've just followed a thread regarding use of CGNAT and noted a suggestion (regarding DANOS) that includes use of DPDK.As I'm interested in the breadth of adoption of DPDK, and as I'm a researcher into energy and power efficiency, I'd love to hear your feedback on your use of power consumption control by DPDK.I've drawn up a bare-bones, 2-question survey at this link:Responses have been set to anonymous.Cheers,Etienne--Ing.
