Hi all,
sorry for my maybe stupid question. I know how to implement stuff according to manuals from the web but I don't understand all technical details.
So I am getting 10 Gbit/s fiber at home now. The pi-hole runs on a raspberry pi which obviously only has 1 GBit/s maximum. Will I still be able to make use of the 10 Gbit/s Network ? I know I have to get new switches, but apart from that? I do not completely understand how much of the traffic goes through the Pi-hole and if it limits the rest of the network.
I tried googling but could not really find anything clear about that.
Appreciate any help in how to best set that up.
That's not obvious at all, as there is a whole range of transfer speeds with different RPi models.
Fortunately, that's not relevant for your question:
Your Pi-hole will only receive your clients' DNS requests, which is but a tiny fraction of your network's overall traffic volume.
Typically, DNS requests are small enough to fit into single UDP packets. Network speed isn't nearly as important as latency here, and that will always be better by one or two orders of magnitude in your local network.
So for DNS resolution in a typical home network, it doesn't really matter how your RPi is connected to your network. That's also true when connecting an RPi via its wifi interface, though I'd still prefer wired over wireless connections, more for stability than for improved latency.
Bandwidth may only become a limiting factor with very large number of active clients sending requests simultaneously. Given the range of CPU architectures and memory sizes that Pi-hole can run on, it's somewhat hard to provide actual numbers, but I don't think you'd notice any bandwidth impact on DNS services with less than 1,000 clients, even on a low end device like a Zero with a 100Mbit NIC.
Hi, thank you very much for the detailed answer. That was what I assumed through my googling I just wasn't 100% sure since some (probably not very educated) technician from the provider was telling me otherwise.
I have the RPi 4 and it is wired. So great to hear, then I can start building the rest and keep that running as is.
