There is no There is no hardware limit, all good all ok, Please tell me what can I do ?

I even set max goroutine to 1500, but no difference

Please tell me what can I do ?

here is test results of my own dns server ( upstream of adguard )

how does dnsmasq, powerdns and unbound compare?

[miladtempaccount]

I get over 70K request per second on my self developed dns server also I get much more on dnsmasq and unbount, please tell me what can I do to increase the speed

It's not using hardware resources, I have enough cpu and ram
