What are you real life Wireguard speeds?

I currently have an Asus router that can’t run Wireguard. I was thinking of looking in to something like this that might work for Wireguard, but I’m wondering about your real life speeds. I know supposedly the Brume can get up to 280 Mbps on Wireguard but my real life numbers might vary. However, I’ve seen some people online using NON GL-iNet stuff who are getting WELL above 400 Mbps. I am just curious what you guys are getting, maybe the 280 Mbps is a technical limitation of the GL-iNet stuff, who knows.
