On the Xeon machine, I was able to get easily to 50Gbps with 4 queues. Is there any specific DPDK configuration that we might want to setup for those AMD servers? The software is DPDK based so I wonder if some build option is missing somewhere. What else I might want to look for to investigate this issue? Thanks -- BR, Filip +48 666 369 823
