Fast fixes you can try now
- Switch to a faster protocol: If you’re on OpenVPN or WireGuard, try switching to WireGuard NordLynx-like in Surfshark, which tends to offer better speeds with solid security.
- Change the server region: Pick a server that’s geographically closer to you or known to be under less load. Avoid high-traffic times if you can.
- Enable the “NoBorders” or “Auto” mode for censorship-heavy regions if you’re in one; this can improve connection stability in some cases.
- Restart the app and/or device: Simple but effective. Clear any stuck connections and refresh routes.
- Disable conflicting background apps: Some apps cloud backups, large syncs, or other VPNs can sap bandwidth. Pause them while you test Surfshark.
- Check router firmware: An outdated router can bottleneck VPN traffic. Update firmware if available.
- Use a wired connection: If you’re on Wi-Fi, try a direct Ethernet connection. Wired tends to be more stable for VPN traffic.
- Optimize MTU: If you’re tech-savvy, dialing in MTU typically 1400–1500 for VPNs can reduce fragmentation and speed up transfers.
- Temporarily turn off IPv6: Some networks speed up with IPv6 disabled when using VPNs that don’t handle IPv6 perfectly.
Speed testing and baseline setup
- Baseline internet speed: Run a speed test without Surfshark active to know your real-world baseline e.g., 100 Mbps down, 20 Mbps up.
- Test with Surfshark on: Run the same speed test with Surfshark connected to different servers to compare.
- Track latency ping: The biggest speed pain for VPN users is latency. A 20–60 ms difference is usually noticeable in gaming and real-time apps.
- Consistency matters: Record your speeds at different times of day to identify if the issue is network congestion vs. VPN bottleneck.
Common culprits and how to tame them
- Server load and distance: The farther, the slower. Pick a nearby server with low latency and check the load indicator in the Surfshark app.
- Encryption overhead: Stronger encryption takes more CPU time. If you don’t need the strongest encryption for casual use, temporarily reduce to a lighter setting during heavy tasks.
- IP leaks or DNS leaks: These don’t directly slow speed, but they can trigger fallback routes that hurt performance. Use Surfshark’s built-in DNS leak protection and always enable Kill Switch during tests.
- ISP throttling: Some ISPs throttle VPN traffic. If you suspect this, try obfuscated servers or different protocols, or test on mobile data to compare.
- Local network congestion: Coexisting devices and bandwidth-heavy activities streams, game downloads, backups can spike latency, reducing VPN performance.
Deep dive: protocol and server tweaks
- WireGuard vs OpenVPN: WireGuard is typically faster and leaner. If you’re on OpenVPN, switch to WireGuard in Surfshark settings to unlock a big speed bump.
- Obfuscated servers: If you’re in a region with VPN blocking or throttling, enable obfuscated servers. They hide VPN traffic in obfuscated packets, often improving speed and reliability.
- Multi-hop mode: Useful for privacy, but it adds latency and overhead. Only use when needed; for speed, stay with single-hop unless you need extra anonymity.
- Split tunneling: If your device supports it, route only the essential apps through Surfshark and let others use direct connection. This can dramatically improve overall speed for non-sensitive tasks.
- DNS settings: Use Surfshark’s DNS or a trusted third-party DNS that’s fast and private. Slow DNS responses can bottleneck perceived speed.
- MTU tuning: For most users, a standard MTU of 1400–1500 works well. If you’re technically inclined, experiment with MTU values in the app or OS network settings.
Hardware and OS considerations Le vpn piu veloci del 2026 le abbiamo davvero provate: confronto completo, test di velocità e consigli pratici
- Router-level VPN: If you’re sharing a network with multiple devices, consider configuring Surfshark on the router. This distributes the VPN load away from a single device and can improve overall home network speed.
- Device performance: Older devices with slower CPUs struggle with VPN encryption. If you’re on a budget device, turn up performance by reducing encryption level for non-critical browsing, then re-enable full security later.
- Background processes: Antivirus or firewall software can slow down VPN traffic by inspecting encrypted packets. Temporarily disable on-device security features while testing speeds be mindful of security implications.
Network environment checklists
- Ethernet vs Wi-Fi: Use Ethernet for steady speeds and lower latency when testing speeds with Surfshark.
- 2.4 GHz vs 5 GHz: If you must use Wi-Fi, 5 GHz often provides better performance and less interference.
- Channel interference: If you’re in a crowded apartment building, switching to a less congested channel can help.
- QoS settings: Some routers prioritize gaming or streaming traffic. If VPN traffic is deprioritized, adjust QoS rules to improve VPN performance during peak times.
- DNS caching: Clear DNS cache on your device to avoid stale responses when testing new VPN routes.

Real-world tips from the field
- Consistency is king: If your speeds bounce a lot, focus on stabilizing your connection first stable router, wired link, fixed server.
- Streaming tips: For 4K streaming, you’ll want at least 25–35 Mbps consistently. If you’re dipping below that with Surfshark, switch to a nearby server and enable split tunneling for HDR content on your streaming device.
- Gaming considerations: Latency matters more than straight throughput. If you play fast-paced games, aim for < 40 ms ping; otherwise, you’ll notice jitter and lag.
