Yes, 100% CPU utilization for DPDK cores. All the drivers are in polling mode, and we bind the thread to certain CPU cores, the core will always polling/working at 100% utilization.

When i run dpdk apps with rte_eth_rx_burst() and rte_eth_rt_burst() within a loop without any sleep, it will occupy 100% of cpu cycles of that core. For example, if I run the kni example app, "htop" command indicates the cpu cores assigned to the kni app are all at 100% ut. Is this expected behavior of DPDK application usage in general? It would be wonderful if you can share some best practices. Thanks
