ControlD slow on the router

I tried ControlD (free) Hagezi Pro Plus on my router and it's noticeable slow, but when I try in Opera as DNS over HTTPS, it's fast.
For comparison, I decided to try AdGuard dns, it's it's fast.
The strange part is that when I do the DNS Benchmark, ControlD shows up as faster than AdGuard:

What can be the cause for this? Maybe when I set it on the router I'm is being routed to the wrong location?
