Hi, I have run multi_process/symmetric_mp example in DPDK example directory. For a one process its throughput is line rate but as I increase the number of cores I see decrease in throughput. For example, If the number of queues set to 4 and each queue assigns to a single core, then the throughpu

performance (roughly 8.5 Gb/s for 8-core). In my scenario Pktgen shows it is generating at line rate, but receiving 8.5 Gb/s. Is it because of Pktgen??? On Aug 28, 2018, at 12:05 PM, Saber Rezvani wrote: On 08/28/2018 08:31 PM, Stephen Hemminger wrote: On Tue, 28 Aug 2018 17:34:27 +0430
