I ran both protocols on the same hardware for two weeks. The speed gap is not small β it's 8x on the same router.
On the GL.iNet Flint 2 β the hardware I tested both protocols on β WireGuard delivered ~810 Mbps. OpenVPN delivered ~95 Mbps on the same hardware, sameβ¦
How much faster is WireGuard than OpenVPN on the same router hardware?
An 8.5x throughput difference was measured on a GL.iNet Flint 2 β WireGuard delivered ~810 Mbps versus OpenVPN's ~95 Mbps on identical hardware andβ¦
On the GL.iNet Flint 2 β the hardware I tested both protocols on β WireGuard delivered ~810 Mbps. OpenVPN delivered ~95 Mbps on the same hardware, same networkβ¦
No β newer isn't less secure here. WireGuard's smaller codebase and modern cryptographic primitives (ChaCha20, Curve25519, BLAKE2) are considered strongβ¦
Why is WireGuard's codebase size relevant to its speed advantage?
WireGuard's codebase is roughly 4,000 lines versus OpenVPN's ~400,000, meaning a smaller attack surface, faster execution, and easier hardware-levelβ¦
For home router VPN use in 2026: almost always. If your router supports WireGuard with hardware acceleration (the GL.iNet Flint 2 does), there is essentially noβ¦
Does the router's chipset play a role in WireGuard's speed advantage?
Yes β the GL.iNet Flint 2's MediaTek MT7986A chipset has hardware-accelerated cryptography specifically for WireGuard's ChaCha20-Poly1305 encryptionβ¦
OpenVPN still has valid use cases, even if they're becoming less common:
No β newer isn't less secure here. WireGuard's smaller codebase and modern cryptographic primitives (ChaCha20, Curve25519, BLAKE2) are considered strong by currentβ¦
Yes β the Flint 2 supports multiple VPN configurations. You can have a WireGuard client active routing home traffic through a VPN provider, while also running aβ¦
