We used a DPDK version of 17.05.2 then 17.08.2. When we want to move to latest DPDK LTS version 18.11, performance seems to be degraded interms of rate. Even for 512B, got this rate reduction issue in transmission. Is it because of any timing APIs changed in 18.11? Tried with DPDK 17.11, got the same problem. When I gone through the documents, not able to find any timer regarding API change or bug fixing. Can any one help me in this regard? Thanks A.Gokilavani
