Hi we are building an application that uses vpp and when I have some questions that concerns multi core usage.
In the run that we are doing now we are using 4 cores and we use some DPDK polling of an interface which makes the cpu load go 100% on all cores. We are interested in energy consumption in the application we are creating and would like to be able to scale up and down the cpu usage during runtime. Is it possible to dynamically change the number of cores used by VPP or specify somehow which cores that are used for polling of an certain interface during runtime? During low and high traffic we would like to scale up and down the amount of cores that is used. If the polling is causing the cpu to go to 100% would it help using Turboboost and Speedstep, would it actually lower the frequency when the traffic is low? BR /Tobias
