> People sometimes ask me to describe the differences between Nebula and Tailscale. One of the most important relates to performance and scale. Nebula can handle the amount of internal network traffic and scalability of nodes (100k+ nodes, constant churn) required on a large network like Slack's, but Tailscale cannot. Tailscale's performance is fine for many situations, but not suitable for infrastructure. It is just a fundamentally different set of goals.
Making broad claims like this without a source or links to benchmarks feels like FUD to me. For example Tailscale's comparison page on performance (https://tailscale.com/kb/1148/tailscale-vs-nebula/#performan...) doesn't mention a meaningful performance difference, so if you're claiming they're not telling the truth (by omission), I'd hope to see more to that than just a straight assertion, even just "We tried Tailscale in Slack's network and it wasn't able to keep up with our usage patterns".
