DNS Benchmark

To check performace of this setup vs popular DNS server:

• Login into PiHole.
• Navigate to Settings > DNS.
• Select predefined upstream DNS servers you want to benchmark against.
• Install namebench or similar script and execute it. Alternatively use PiHole for 24 hours.
• Find PiHole container id docker ps -a.
• Access PiHole container docker exec -it <container-id> sh.
• Execute echo ">forward-dest >quit" | nc 127.0.0.1 4711 to get percentage of forwards to each server (PiHole has an algorithm which will favor the best performers. The best performers will get the most forwards.)
