Body Which nordvpn subscription plan is right for you 2026 guide: Smart Picks, Plans, and Tips for 2026

1. Quick diagnostic: is Surfshark slow, or is your whole internet slow?

• Run a baseline: Perform a speed test on a wired connection without VPN to get the baseline aim for at least your advertised ISP speed. Then test again with Surfshark connected to a nearby server.
• Compare results: If your baseline is 200 Mbps and VPN drops to 20–30 Mbps, you’ve got a VPN bottleneck. If baseline is 100 Mbps and VPN is 90 Mbps, the problem lies elsewhere.

2. Server selection: pick the right server for speed

• Use nearby servers: The closer the server, the lower the latency. Start with a server in your region or the next closest country.
• Try different provinces or cities: Sometimes one city is congested but another nearby one isn’t. Test 2–3 servers to compare speeds.
• Don’t rely on auto-selection alone: Auto-select can pick a busy server. Manually choose a less crowded one, even if it’s a bit farther away.
• For streaming and gaming: Look for servers labeled optimized for streaming or gaming if available, but verify speeds first.

3. Protocols: speed vs. security trade-offs

• WireGuard or similar lightweight protocol: Fastest and most reliable for many users, good balance of security and speed.
• IKEv2: Good stability and decent speed on mobile devices; might be slightly slower on some desktops.
• OpenVPN UDP: Very secure, but can be slower on poor networks.
• How to switch: In Surfshark, go to Settings > VPN Protocols and try WireGuard first, then test IKEv2 or OpenVPN UDP if needed.
• Quick tip: If your device supports it, keep the protocol consistent across apps to reduce negotiation overhead.

4. Kill background activity and reduce overhead

• Close unnecessary apps: Streaming apps, cloud backups, and syncing services can hog bandwidth even when VPN is active.
• Pause downloads: If you’re downloading large files, pause while testing VPN performance.
• Check for browser extensions: Some extensions can leak DNS or add overhead. Disable nonessential ones while testing VPN speed.

5. DNS and tunneling adjustments

• Use Surfshark DNS: Ensure DNS is handled by Surfshark’s DNS or a trusted alternative to avoid DNS leaks. This can improve reliability and speed in some networks.
• Enable private DNS on-device: Some devices embed their own DNS caching. You can switch to Surfshark DNS in the app or OS DNS settings to reduce lookup times.
• Split tunneling if available: Some users see speed gains by excluding non-critical apps from the VPN tunnel. This keeps essential apps secure while streaming or gaming get the full bandwidth.

6. Router-level optimization for home networks

• Reboot your router: A simple restart can clear cache and improve routing efficiency.
• Firmware updates: Ensure your router firmware is current to maximize VPN compatibility and speed.
• MTU settings: If you’re comfortable, adjust MTU to reduce fragmentation; start with the default 1500 and experiment in small increments 1492, 1476 while testing speed and stability.
• Use a wired connection: If possible, connect your primary device directly via Ethernet to minimize Wi-Fi overhead.
• QoS configurations: If your router supports QoS, prioritize VPN traffic or gaming/streaming to reduce jitter and improve apparent speeds.

7. Device-specific tips

• Windows/macOS: Ensure the latest OS updates to fix networking issues that can affect VPN performance.
• iOS/Android: For mobile devices, test over both Wi-Fi and cellular; sometimes cellular networks handle VPN routing differently and may offer faster results.
• Background apps: On mobile, check battery saver modes or VPN-related permissions that might throttle traffic.

8. ISP considerations and throttling

• ISPs sometimes throttle VPN traffic during peak times. If you suspect this:
  • Test at different times of day to compare.
  • Run a traceroute with and without the VPN to see where traffic slows.
  • Consider switching servers in another region to see if you bypass throttling routes.
• Carrier-specific tips: Some carriers have flags that treat VPNs differently; using a protocol like WireGuard may bypass some throttling patterns, while UDP-based OpenVPN might get slower.

9. Common performance myths debunked

• More servers equal faster speeds? Not always. A nearby, lightly loaded server often beats a far-away, loaded one.
• VPNs always slow you down by 10–20%? Real-world results vary widely; many users see 20–60% impact depending on protocol, server load, and network conditions.
• Free VPNs are always slower? Not necessarily, but the quality of the service matters. Surfshark’s paid plan tends to offer more reliable routing and fewer bottlenecks.

10. Real-world test plan step-by-step

• Step 1: Connect to the nearest Surfshark server. Run a 2-minute speed test baseline 3 tests and record results.
• Step 2: Switch protocol to WireGuard and re-test. Note the delta in Mbps and latency ms.
• Step 3: Try a second nearby server and compare results. Repeat with IKEv2 and OpenVPN UDP if needed.
• Step 4: If using split tunneling, disable it and test again to compare performance.
• Step 5: Reboot your device and router, re-test to confirm improvements are consistent.

11. Data-backed performance guidance

• Typical VPN speed ranges:
  • Local VPN server same city: 70–95% of baseline speed on WireGuard for many users.
  • Nearby servers within 50–100 miles: 50–85% of baseline depending on congestion.
  • Distant servers: 20–60% of baseline, sometimes less during peak times.
• Latency changes: VPN can add 20–100 ms to ping depending on server distance and routing quality.

12. Safety and privacy sanity checks

• DNS leaks: Run a DNS leak test after enabling Surfshark DNS to confirm your queries aren’t leaking to your ISP.
• WebRTC leaks: If you’re on a browser that’s prone to WebRTC leaks, consider disabling WebRTC or using a browser that limits leak exposure.
• Kill switch: Ensure Surfshark’s kill switch is enabled so you don’t accidentally leak traffic if the VPN drops.

13. Advanced tips for power users

• Combine VPN with a content delivery network CDN aware hosting: If you’re streaming locally, using a region-appropriate CDN can improve streaming stability even if you’re routed through a VPN.
• Scripted tests for consistency: Use a simple script to ping a fixed set of servers and log latency and jitter for ongoing monitoring.
• Regular maintenance cadence: Once a week, run the speed test routine to catch slowdowns early.

14. Common issues and quick fixes

• Issue: VPN disconnects during gaming
  • Fix: Try a different protocol, enable the kill switch, and ensure your router doesn’t have aggressive firewall rules.
• Issue: Streaming buffers frequently
  • Fix: Switch to a nearby server and enable environmental optimizations like pre-buffering if available in the streaming app.
• Issue: VPN speeds randomly drop
  • Fix: Reboot devices, update Surfshark app, and switch servers or protocols.

15. Tools and resources to stay on top

• Speed test tools: Ookla Speedtest, Fast.com
• DNS test: DNSLeakTest.com
• Traceroute tools: Windows tracert, macOS traceroute, Linux traceroute
• Networking basics: your router’s admin page, OS network settings

FAQ Frequently Asked Questions

Why is Surfshark slower on some devices?

Surfshark speed can vary by device due to CPU power, background processes, and protocol negotiation efficiency. Try switching protocols, testing nearby servers, and ensuring no other apps are hogging bandwidth.

How do I choose the best Surfshark server for speed?

Start with the nearest server, then test 2–3 additional nearby options. Look for servers labeled for streaming or gaming, but prioritize actual speed results from your tests.

Which protocol is fastest with Surfshark?

WireGuard is typically the fastest and most reliable for most users, followed by IKEv2 on mobile. OpenVPN UDP is slower but offers strong security.
