Hi,

During performance analysis testing with the Intel NIC and DPDK version 20.11.2 , we are seeing high latency numbers in 00000000009e4fe2 <_ice_recv_raw_pkts_vec_avx2>: that I’m trying to understand if this is a known or expected issue. Our test consists of running high rates of RTP media for a small period of time. Running the same test using a 520 NIC shows a performance improvement.

Please see attached vtune screenshots for details.
Any thoughts would be greatly appreciated!

Thanks,
Steve
