[Public] Hi @Morten Brørup, please find our observation running testpmd with memif in zero-copy mode disabled (rte_memcpy enabled).
1. DPDK baseline version: 25.11 we tested with testpmd in io & flowgen mode 2. using no cargs for memcpy (rtemov32) and with patch 64B & 65B we get `15.5Mpps` 3. using cargs ` -DRTE_MEMCPY_AVX512` for memcpy (rtemov64) and with patch 64B & 65B we get `14.8Mpps` We will run with dma-perf application for payload sizes of 1,2,3,4,5,...etc Regards Vipin Varghese
