Horrible LAN throughput using RB564 daughterboard

Does anyone else use the RB564 daughterboard with a RB532? I’m running version 5.19 of ROS and when I transfer files from one machine to another that is connected to the daughterboard it’s uber slow (avg ~3-6Mbps) and the latency always remains low (<=1ms). I then tried to just plug it directly into one of the ports on the RB532 and the throughput was 50Mbps+. Is this normal or a bug with ROS? Maybe I just need to buy a newer Routerboard, lol.
