the throughput is only providing 50 MB which can create some issues with some internet websites, it doesn't matter if you have a 1000 MB fiber circuit the router is only able to provide 50 MB. The fix you need is to have a better router that is able to deliver more throughput. The switches are not the problem each port is able to provide up to 1000 MB per port.
