It is currently in alpha, but progressing fast and getting close to a point where it can be used for production workloads. Rewriting existing software systems is a special kind of hard. Aside from the difficulty in writing the software itself, you have to deal with behaviors of the existing system tha

Linux kernel WireGuard can go 'fast' on decent hardware
