With payload on one port throughput is ~9500Mbit/s for read and ~9500Mbit/s for write. With payload on two ports throughput is ~7000Mbit/s for read (on both ports) and ~9300Mbit/s for write (on both ports). I'm sure that the CPU cores socket id is the same as NIC socket id and that CPU is not a bottleneck. Suppose that bottleneck is NIC or PCI (I'm using PCIe x8). Can you tell me please, is it the maximum troughput that available for my NIC? Thanks
