Hi, Distributor library only takes care of load distribution based on flow type i.e. based on rss ( which is calculated based on 5 tuple of the packet) value of mbuf to workers. Packets with same rss will be given to same worker. Hence different flows goes to different workers. 15.5 mpps was the performance we achieved with 8 worker cores, 1 Rx core and 1 TX core using sample application. Thanks, Reshma
