These five pages cover most of what people arrive looking for.
- How a Tailscale mesh VPN works
The model underneath everything else: coordination plane, NAT traversal, DERP relays, identity-based access rules.
- Tailscale setup guide
Install to first tailnet in the order the decisions actually arrive, including closing the allow-all policy a new tailnet ships with.
- Why Tailscale throughput is slow
Diagnose in priority order: relayed path first, then NAT traversal, then offload, CPU and whatever is forwarding in the middle.

Control plane ownership, network layer and policy model are the three questions that decide it. Headscale placed as well.
- Latency and throughput estimator
Put your own measured baseline against direct, peer-relay and DERP paths and see which ceiling is binding.
