I have made changes to the test pipeline application such that for EVERY port instance there are 3 cores: Rx Core, Worker Core and Tx Core instead of ALL ports mapping to a single Rx/Tx Core like in the original implementation. This is being done to try and increase the overall throughput of the application. In the app_main_loop_worker_pipeline_hash function, I am instantiating a new pipeline instance for each port and stitching the rings_rx and rings_tx accordingly. With these changes I am able to get a throughput of ~13Mpps on one 10G port. But, when I send a high rate traffic (13Mpps each) from BOTH the ports simultaneously, the traffic stops completely. Stopping the restarting traffic doesn't seem to be helping. It almost looks like the pipeline is locked up and not seeing any packets in the Rx rings. Has anyone encountered this before ? Any idea how to debug/what could be going wrong ? Appreciate your help ! Regards, Vijay
