You may want to give more details, NICs used, setup of hardware, what is the host system used, how is the generator sending packets (fixed packets or modified on the fly, …) What was the performance difference with the DPDK versions you tried? Have you tried Pktgen, TRex or testpmd to see if they have the same performance problem? > > > Thanks > > A.Gokilavani Regards, Keith
