So I am thinking about running Pi-Hole. I have been using NextDNS as a solution to avoid doing that, but now I’ve started realizing that it’s featureset is limiting me vs what Pi-Hole can provide. My only problem is that the Raspberry Pi that I would use for that is limited to 1gig interface, and my network runs as a 2.5G network - even the uplink to my ISP (technically 3Gb, but my interfaces limit me to 2.5G and my ISP doesn’t provide a 2Gb plan). Would the DNS server running on a Raspberry Pi slow down all queries or just when I hit the DNS request? I feel like it wouldn’t really affect most things - not that a huge amount of internet infrastructure can provide me content at 2.5Gb
DNS is just kilobytes of data used for DNS lookup so you are far far below the 1GB link being the limitation. What you do notice with DNS is latency. Most modern sites are not just one, but many lookups and any delay in those lookups make each page or pars of a page take longer to load. The PiHole should be fast enough without any issues.
