Thanks chenxndsc for the response. Yes, the polling shall take the 100% CPU. My question is related to know how much more load a core can take more. For e.g. Lets say along with normal dpdk polling, if a core processeses few sessions, how much CPU it takes in processing sessions apart from polling. This is required to know how many sessions a can handle and hence how many cores are needed to handle desired number of sessions?
