Comment on Tips on speeding up remote connection to personal server?
wilo108@lemmy.ml 4 hours agoConnecting to my N100-based box on my LAN is measurably (and noticeably) slower over tailscale than without. The encryption overhead is not nothing, and it can be meaningful depending on CPU hardware. (To be clear, not OP’s problem, just commenting on “Tailscale on itself isn’t a measurable overhead.”)
No, really, wireguard encryption overhead is negligible unless you have a really old CPU (like a Pentium100 or something).
Whatever slows down your N100 is not wireguard per se, probably some tailscale overhead going trough their servers.
I have a fairly dated rented server, with an Atom D510, 2 cores, which is 10 years old, and accessing it over wireguard or not, I can still max out the network bandwidth without any visible CPU overhead.
