when I want to measure the network bandwidth with the iperf3 package running iperf3 directly on the router (WDR4300 and Acer C7 v2).
Router <-- 1G --> PC
I only can measure a maximum bandwith of < 200 Mbits/sec.
With the setup
PC <-- 1G --> Router <-- 1G --> PC
I can measure a maximum bandwith of ~ 950 Mbit/sec.
