Pi-hole on Rpi and impact on web page loading speed?

Question

Raspberry Pi

Installed on Raspbian lite - PI-HOLE. Assigned a static IP address to the device. I use wi-fi as a network interface on Raspberry Pi.
On two other devices: the computer is connected to the router via lan cable, the smartphone via wi-fi. As dns registered ip address RPI.
How do you think it will affect the speed of loading Internet pages on a computer and content in android applications due to the fact that the RPI is connected via wi-fi?
Maybe you should use the ethernet port of the raspberry to connect to the router?
Once again I clarify that the main gateway on the computer and smartphone is the address of the router, and only DNS is chasing through the raspberry.

Answer 1

Ideally, of course, it is better to connect via cable.
And not because DNS traffic is negligible compared to the main stream, but because of WI-FI standard collisions - the fewer devices connected to the point, the more bandwidth they get.
And since the raspberry can be placed near the router and also powered from its USB, the 10cm patch cord is ideal here.
From the Raspberry side, it doesn’t matter, both wi-fi and ethernet go through usb-hub, but speed and stability will be higher on ethernet.
IMHO: I am for everything stationary, only for a closed transmission medium (wire). Because WI-FI, especially 2.4, especially in high-rise buildings, is now so crowded that you can rarely get good speed even on normal routers.
