Latency with pi-hole + wireguard (docs.pi-hole.net)

Hi guys for those of you that use pi-hole (or similar solutions like adguard home, etc) and wireguard how far away can you be from your wireguard/pi-hole server before latency becomes a major issue?

Also on a side note how many milliseconds of latency would you guys consider to be to slow?

Edit I meant dns latency sorry for not mentioning

Depends on your use case there are multiple factors that guide internet use cases

Latency - how fast
Bandwidth - how wide/much
Loss - how much data is lost, or how much data needs to be sent again

Gaming: latency, loss

YouTube/movies: bandwidth

Video chat/voice chat: latency, bandwidth

Remote desktop/game streaming: latency, bandwidth, loss

Web browsing: bandwidth, latency

DNS latency can be a multiplier for browsing the web, a website can include artifacts from other websites, which then can include other websites, which then can include other websites. Each one of those would require another DNS lookup, and round trip time to the website itself etc. however, DNS was architected for local caching, so only the first lookup should be slow, and then afterwards you should keep that DNS information for future lookups so it's not going to feel too bad once you've warmed up the cache

Rule of thumb: under 100ms feels fine, over starts to feel a little sluggish. Over 300ms and you change your behaviors, and you really feel it.
