An ops engineer had OpenVPN running for remote access. Config files were 200 lines. Every new hire took 30 minutes to onboard.
The VPN Complexity Problem
OpenVPN is bloated. IPSec is worse. WireGuard has about 4,000 lines of code vs 100,000+. Faster, simpler, built into Linux kernel.
What WireGuard Offers for Free
- Kernel-Level Speed - Near-wire-speed performance
- Simple Config - Each peer is about 10 lines
- Modern Crypto - ChaCha20, Curve25519, BLAKE2s
- Roaming - Change networks without dropping tunnel
- Cross-Platform - Linux, macOS, Windows, iOS, Android
Performance Comparison
| Protocol | Throughput | Config Lines |
|---|---|---|
| WireGuard | ~900 Mbps | 10 |
| OpenVPN | ~400 Mbps | 200+ |
| IPSec | ~700 Mbps | Complex |
