Tailscale isn’t really that slow once you connect it creates direct connections between nodes. There is some latency when you first connect like 100ms before derp lets the nodes directly connect. I get full link level throughput between oci nodes and my house/cellphone. I even went so far as disabling all external ports on my cloud instances.
