VPN Connection Speed: What Affects VPN Performance

Factors That Affect VPN Speed

Server Distance: The physical distance between you and the VPN server is the biggest factor. A server in Vancouver will be much faster for someone in Toronto than a server in Japan. Always choose the closest server for best speeds.

VPN Protocol: WireGuard is 30-50% faster than OpenVPN. IKEv2 is also very fast. OpenVPN TCP is the slowest due to the TCP-over-TCP problem. Choose WireGuard whenever possible.

Encryption Level: AES-256 is the standard and has minimal impact on modern devices with hardware acceleration. Older devices without AES-NI support may see more significant speed reduction.

Server Load: A crowded server with thousands of users will be slower than a lightly loaded one. Premium VPNs display server load percentages so you can choose optimal servers.

Your Base Internet Speed: If your base connection is 50 Mbps, a 10% VPN overhead leaves you with 45 Mbps. If your base is 500 Mbps, 10% overhead leaves 450 Mbps. Faster base connections better absorb VPN overhead.
