Hello all,

today I was struggeling with very low speeds on the Archer VR2100v even all devices connected were supporting 1GBit/s Ethernet. The network speedtesting tool "iperf" were showing me approx. 300MBit/s instead of expected >900 MBit/s. However, I ended up with the setting "Traffic Monitor" (Advanced Settings -> System Tools)  which I activated couple days ago... Disabling the "Traffic Monitor" allows the expected >900 MBit/s in my case. Unfortunately, in the "Help (Question Mark on the setting sides) does not tell that activating "Traffic Monitor" can slow down Ethernet speed by factor 3... As a "newbie" in network topics, I did not believe that Traffic Monitor can slow down the Ethernet speed significantly... 

Hope this information will prevent other newcomers stepping into the same trouble.

Best regards,
