packet
- Kernel networking stack is the one allocating the packet buffers,
WireGuard doesn't allocate anything on top of this
- WireGuard overhead = UDP header + WireGuard = 60 bytes
- WireGuard overhead: ipv4 header (20 bytes) + udp header (8 bytes) + wireguard header (4 byte type, 4 byte keyid, 8 byte nonce, 16 byte authtag = 32 bytes) = 60 bytes
- performance
- fast, no copies across \*space
- ChaChaPoly is fast
