WireguardTCP: WireGuard over TCP
TL;DR
WireGuardTCP introduces an opt-in TCP transport for the Linux WireGuard kernel module, achieving competitive performance against traditional UDP mode. In tests, TCP mode delivered 152.55 requests per second at 0% loss, outperforming UDP in low-latency scenarios.
✦ Why It Matters
Consider testing WireGuardTCP in your applications to evaluate its performance benefits over UDP.
Key Takeaways
- Test WireguardTCP in your environment to assess performance gains.
- Maintain UDP as the default unless specific conditions favor TCP.
- Monitor request rates to determine the best transport method.
- Stay updated on precompiled releases for easy implementation.
How It Works
WireguardTCP encapsulates handshakes, keepalives, and encrypted data within a long-lived TCP stream, allowing for reliable data transmission while preserving WireGuard's encryption. The framing checksum identifies record boundaries, ensuring that WireGuard's authentication mechanisms still govern trust.
