Quick Wins to Stop Surfshark from Slowing You Down
1. Check for a VPN speed baseline
- Run a baseline speed test without the VPN to know your normal speeds.
- Run a Surfshark speed test on the same server you usually pick, and note the difference.
- Tip: If there’s a huge drop, focus on obvious culprits next server choice, encryption, or device restrictions.
2. Switch to a nearby server
- Proximity matters. Pick a server in your country or a neighboring one for the best balance of speed and access.
- If a nearby server is slow, try a different city within the same country. Don’t stick to a single server if it’s dragging.
3. Change VPN protocol
- Surfshark offers multiple protocols WireGuard, IKEv2, OpenVPN, etc..
- WireGuard usually wins on speed and modernity, but some networks perform better with IKEv2.
- How to switch: Open Surfshark app > Settings > VPN Protocol > choose WireGuard or IKEv2. Test speed after each switch.
4. Disable battery-saver features and background apps
- On laptops and phones, battery-saving modes throttle network performance and VPN reliability.
- Close apps that drain the network or compete for bandwidth while you test VPN speeds.
5. Disable IPv6 if you’re not using it
- Some networks handle IPv4 much better, and IPv6 can cause routing quirks with VPNs.
- In Surfshark: Settings > Network > IPV6 and disable if not needed.
6. Use a wired connection when possible
- Ethernet connections reduce interference and packet loss compared to Wi-Fi, especially on crowded 2.4 GHz bands.
- If you’re on Wi-Fi, move closer to the router or switch to 5 GHz if supported.
7. Reboot the router and your devices
- A quick reboot can clear stuck processes and reset your connection pathways.
- After reboot, test speeds again to confirm improvement.
Advanced Network Tweaks for Speed Boost
8. MTU considerations
- If MTU is too high, you’ll see fragmentation and slower speeds; too low, you’ll lose efficiency.
- Typical MTU values: 1500 for Ethernet, 1472–1476 for VPNs. You can test MTU by trial and error or use online MTU calculators.
- How to adjust: Router admin page > WAN/Network > MTU or via device VPN config.
9. DNS matters
- Slow or congested DNS can make loading look like VPN issues even when data is flowing.
- Use a fast public DNS e.g., Google DNS 8.8.8.8 and 8.8.4.4, Cloudflare 1.1.1.1 in your device or router settings.
- Surfshark also provides its own DNS; enabling it can improve privacy and sometimes speed.
10. Split tunneling where available
- If only a subset of apps needs protection, consider using split tunneling so critical apps don’t go through the VPN.
- This reduces tunnel load and can improve perceived speed for non-critical tasks.
11. Check for firewall or antivirus interference
- Some security software inspects VPN traffic, adding overhead.
- Temporarily disable real-time scanning to see if speeds improve. If they do, adjust the software rules to exclude Surfshark traffic.
12. Optimize router hardware and firmware
- Ensure your router’s firmware is up to date to avoid known performance issues.
- Enable QoS Quality of Service to prioritize VPN traffic if your router supports it.
- If you have an older router, consider upgrading to a model with better VPN handling and higher CPU performance.
13. Use a VPN-compatible router for all devices
- A dedicated VPN router lets you run Surfshark at the network edge, reducing device-level overhead.
- It also keeps all devices protected without relying on apps that might throttle on busy devices.
14. Check for bandwidth-sapping devices on your network
- If someone in your house is streaming, gaming, or downloading large files, speeds can plummet for everyone, including VPN traffic.
- Pause or limit other heavy users while you test Surfshark speeds.
Device-Specific Tips
15. Windows/macOS tips
- Ensure you’re on the latest OS version and Surfshark client.
- Disable background apps that auto-update while you test VPN speed.
- Use a clean boot to rule out other software conflicts.
16. iOS/Android tips
- Check battery saver and data saver modes; disable them during VPN testing.
- Toggle Smart Network Switch or similar features off if your device aggressively switches between networks.
- Keep the app updated to the latest version for performance fixes.
Real-World Data and Benchmarks
Typical speed expectations
- With a fast, close server and WireGuard protocol, you can expect 70–95% of your non-VPN speeds for light browsing and streaming at 1080p, and 40–70% for 4K streaming depending on server load and congestion.
- On distant servers or with older protocols, expect more variability and potential drops of 20–50% or more.
Streaming and gaming benchmarks
- Streaming: 1080p usually smooth on nearby servers; 4K may require a nearby server and solid bandwidth at least 25 Mbps real-world VPN speed.
- Gaming: Low-latency connections matter more than raw bandwidth; WireGuard generally offers the best balance for latency-sensitive gaming, but the server you pick matters most.
Network health indicators to watch
- Packet loss over VPN: aim for under 1% on wired connections; higher losses indicate congestion or routing issues.
- Latency ping: sub-30 ms is ideal in many regions; VPNs will add tens of milliseconds, which is normal but should remain stable.
- Jitter: keep jitter under 5 ms for a smooth experience.
Practical Troubleshooting Flow
- Run a baseline speed test without VPN.
- Connect to the closest Surfshark server; test.
- If slow, switch protocol WireGuard -> IKEv2 or vice versa and test again.
- Try a different nearby server if still slow.
- Check MTU and DNS settings; adjust if necessary.
- Reboot router and device; test again.
- Consider a dedicated VPN router if speeds remain inconsistent.
Common Mistakes That Kill VPN Speed
- Sticking to a single server regardless of load.
- Not updating the Surfshark app or device OS.
- Ignoring the impact of local network congestion.
- Forgetting to optimize MTU and DNS.
- Overloading the network with other heavy activities during speed tests.
Data-Driven Tips to Maintain Speed Over Time
- Regularly rotate servers to avoid persistent congestion.
- Schedule large downloads during off-peak hours to maintain steady VPN performance.
- Monitor your home network’s throughput with a simple speed-test routine and adjust server choices accordingly.
Security Considerations While Speed-Boosting
- Don’t disable essential protections for the sake of speed; prioritize a balance between privacy and performance.
- If you use split tunneling, ensure the chosen apps are truly safe to exclude from VPN protection.
- Always keep Surfshark app and firmware updated to mitigate vulnerabilities.
Quick Reference Checklist
- Test baseline speeds without VPN.
- Choose a nearby server and test.
- Switch protocols and test again.
- Check MTU and DNS settings.
- Use wired Ethernet if possible.
- Reboot devices and router.
- Update all software and firmware.
- Enable QoS if supported by router.
- Consider a VPN router for system-wide coverage.
Frequently Asked Questions
How can I speed up Surfshark VPN on my iPhone?
Use the WireGuard protocol, try a nearby server, ensure you’re on a stable Wi‑Fi network, disable battery saver, and keep iOS updated.
Does using Surfshark slow down my internet?
Yes, VPNs add some overhead, but you can minimize it with nearby servers, WireGuard, and optimized DNS/MTU configurations.
Why is Surfshark so slow on Windows but fast on Android?
This can be due to device-specific background processes, firewall settings, or router QoS. Check protocol, MTU, and DNS; update drivers and app.
Is WireGuard faster than OpenVPN with Surfshark?
Generally, yes. WireGuard is lighter and more efficient, but some networks perform differently; test both to confirm.
