Hi, I have an application over dpdk which is consisted of the following threads each running on a separate core: 1) rx thread which listens on in a poll mode for traffic 2) 2 packet processing threads (for load balancing) 3) kni thread (which also runs on a separate core).
the rx thread receives packets and clones them and transmit a copy to the kni and the other packet is sent to the packet processing unit (hashing over 2 threads). the receive traffic rate is 100Mbps. When working with single packet processing thread I am able to get all the 100Mbps towards the kni with no drops. but when I activate my application with 2 packet processing threads I start facing drops towards the kni. the way I see it the only difference now is that I have another threads which handles an mbuf and frees it once processing is completed. Can anyone assist with this case please? Thanks!
