Edgeroute er-x network speed issues

[skveen]

Hi,
everyone
I got a new device Edgeroute er-x。
version of openwrt is v21.02.5

Our network speed is gigabit and the switch port is also gigabit
When not passing the Edgeroute test, the network speed is normal (1Gb), but after passing the Edgeroute, the network speed is only 200M. Make sure that no tools such as speed limit are used. What is the problem? How to troubleshoot

Thanks.
