[Public] Hi Wang,
We use dpdk dma-perf application for testing memcpy via cpu. Please find the ini configuration shared below ``` [GLOBAL] eal_args=--in-memory --file-prefix=test -l 34,35 cache_flush=0 test_seconds=10 [case1] type=CPU_MEM_COPY mem_size=100 buf_size=1,17,1,ADD src_numa_node=0 dst_numa_node=0 lcore=35 ``` Please adapt eal_args and lcore for machine on which you are running. Command used is `dpdk-vanilla/build-no512/app/dpdk-test-dma-perf --config ../config.ini --result /tmp/memcpy.log` After running we rebuild dpdk to use avx512 MEMCPY using `-DRTE_MEMCPY_AVX512` and then rerun the dma-perf again.
