Interesting... looks like a nice little box alright... In its sepc (https://i.mt.lv/routerboard/files/hEX-161103103915.pdf), it mentions that the bridging and routing speed for small packets (64 bytes) is about 530mb/s... its only larger packet sizes that is higher (nearly 2gb a sec).
You mention iperf... wondering what the size of the packets are there. Second, is it routing that is being done? Are there firewall rules? Could you do a full export of the firewall part? I am in the process of upgrading my network from a Mikrotik Cloud Router (vm on a machine) to a physical one (possibly a CCR1016-12G) and want to get line rate between the ports, even though they will be separate vlans too...
