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!
