Performance and capacity planning

Performance depends on hardware, network conditions, and VPN configuration. Here are practical guidelines and data points to help you plan. Nordvpn ip adressen erklart shared vs dedicated war du wirklich brauchst 2026

• CPU: VPN encryption and tunnel handling are CPU-bound. Modern CPUs with AES-NI help, but WireGuard still tends to outperform OpenVPN in typical setups.
• RAM: A stable baseline is 1–2 GB for moderate loads; scale up if you expect heavy concurrent connections or site-to-site tunnels.
• Network: The VPN’s throughput will be limited by both WAN bandwidth and the CPU’s ability to encrypt/decrypt traffic. Consider enabling hardware acceleration if your platform supports it.
• Latency: WireGuard usually introduces lower latency due to its efficient protocol design. OpenVPN can add more overhead depending on TLS and cipher suites.
• TLS/cryptography: If you’re using OpenVPN, choosing modern ciphers and TLS 1.3 where available helps with performance and security.

Testing tips:

• Use iperf3 between sites to measure raw bandwidth before and after VPN setup.
• Run curl speed tests from clients behind the VPN to gauge real-world performance.
• Monitor CPU, RAM, and network interfaces during peak times to identify bottlenecks.

Benchmark example hypothetical:

• OpenVPN on a mid-range x86 CPU with AES-256-GCM: ~600–900 Mbps tunnel throughput under ideal conditions
• WireGuard on same hardware: ~1–2 Gbps, depending on NIC and MTU
• IPsec/IKEv2: ~700 Mbps to 1.5 Gbps depending on hardware acceleration

Note: These figures vary widely. Always test in your own environment.

Security best practices

• Use strong authentication:
  • WireGuard: rely on public keys; keep private keys secure.
  • OpenVPN: strong TLS certificates, use TLS-auth or TLS-crypt for an extra layer.
  • IPsec: strong pre-shared keys are discouraged; prefer certificates or EAP methods.
• Enforce encryption:
  • Use modern ciphers AES-256-GCM, ChaCha20-Poly1305 where available
  • Enable Perfect Forward Secrecy PFS for OpenVPN/IPsec configurations
• Network segmentation:
  • Create separate VPN networks for admin, users, and guest traffic
  • Route only necessary subnets through the VPN
• Access control:
  • Use client-specific rules, firewall rules, and traffic shaping to limit exposure
