That’s definitely cool to see! I’ll be interested to see how much the performance can be improved. The per-core performance of ZeroTier is actually quite good in my experience, so being able to scale to more cores should really unlock a good bit of performance. It’s not apples to apples, but I got near linear scaling when adding more cores. Between a 4-5 times speed improvement by forcing ZeroTier to use multiple cores in a routed environment.
