My PiHole use enterprise grade server and located at data center, it meant to serve tens of millions of requests in a day while my AdGuard use old small-form-factor PC and way far from Indonesia Data Center. Yes, I install them with same virtualization technology, but hardware and infrastructure where my PiHole and AdGuard installed is different. I can't compare PiHole and AdGuard performance (my previous article) with my current resources. Just run PiHole install script ( curl -sSL | bash) and you are ready to go. The installation process also quite straightforward like AdGuard Home installation process. Installed on LXC with just 4 cores of Xeon CPU and 4GB of RAM it can easily handle 10 million queries per day (although on average, my PiHole only serves 2.5 - 5 million requests per day).

In terms of reliability, I think PiHole definitely deserves a mention. During 4 years using PiHole, I rarely experienced significant problems in maintenance, upgrade or troubleshoot process. I was using PiHole as DNS forwarder and DNS sinkhole of my main DNS servers (BIND). Regarding my previous post about Mikrotik, DNS-over-HTTPS and AdGuard, there is one product that I actually used several years before.
