What exactly causes Surfshark to feel slow?
- Server distance: The farther you are from the VPN server, the more latency you experience.
- Server load: Popular servers can be crowded; timing matters.
- Protocol choice: Some protocols are faster but less secure than others; your network might favor one over another.
- Local network issues: ISP throttling, router settings, or congestion can drag VPN speed down.
- Device performance: Older devices or apps running in the background can bottleneck performance.
- DNS leakage or misconfigurations: DNS routing problems can slow things down or cause failures.
- Multihop or obfuscated mode: If you’re using advanced features, they can impact speed if not needed.
Key stats you should know
- Typical Surfshark speed reduction: on average, many users see 10–40% slowdowns compared with baseline speeds when using a VPN, depending on distance and server load.
- WireGuard often yields the best speed among Surfshark options, with performance gains of 20–50% in many test scenarios vs OpenVPN.
- Distances and bandwidth caps are real: if you’re streaming 4K video, a near-server with a stable connection is generally best.
Section: Quick wins you can try today
- Server proximity: Switch to a server within 50–100 miles if you’re in a densely populated area. If you’re abroad, try a nearby regional hub first before jumping continents.
- Protocol swap: Start with WireGuard WireGuard/X-25519 is Surfshark’s default in many apps and compare to OpenVPN UDP. If you’re on a mobile network behind strict firewalls, OpenVPN might be more reliable.
- Enable Smart Protocol: If your device supports it and your network is inconsistent, Smart Protocol can auto-tune for speed and stability.
- Turn off energy-saving mode: Some devices throttle network performance when battery saver is on.
- Close background apps: Pause or quit apps that use large bandwidth while you test VPN speed.
- Restart devices and router: A quick reboot can clear stuck processes and refresh network routes.
Section: Step-by-step fixes by scenario
Scenario 1: You’re seeing slow speeds on a fast home network Surfshark vpn port forwarding the ultimate guide to getting it right
- Check baseline: Run a speed test with no VPN to confirm your normal speeds.
- Switch to a nearby Surfshark server: Use auto-optimize if available or pick a closer city.
- Protocol test: Compare WireGuard vs OpenVPN UDP for speed and stability.
- Disable IPv6: Some networks work better with IPv4 when using VPNs; turn off IPv6 in the Surfshark app and on your router if you don’t need it.
- DNS settings: Use Surfshark’s private DNS or set a known fast DNS like 1.1.1.1 on your device.
- Router-level VPN: If you’re routing traffic through a VPN from the router, ensure the firmware is up to date; use a router that supports VPN pass-through without bottlenecks.
Scenario 2: You’re on a mobile plan and seeing throttling
- Test on different networks: Try Wi-Fi vs cellular. If cellular, switch to a different cell tower or network 5G vs 4G and see if performance improves.
- Protocol selection: WireGuard usually works best on mobile networks; test both WireGuard and OpenVPN.
- Battery and performance modes: Turn off battery saver, and ensure the VPN has permission to run in the background.
- Background data: Ensure the VPN app isn’t restricted by data saver settings in Android or iOS.
Scenario 3: You’re streaming, but video buffers or stutters
- Server load and location: Try a server known for streaming in the same region as the content.
- Enable streaming-optimized servers if available: Surfshark sometimes updates optimized servers for streaming platforms.
- Try a different streaming protocol: Some streaming services perform better on WireGuard; others with OpenVPN UDP.
Scenario 4: You’re on a restricted or hostile network work/school
- Obfuscated servers: Turn on Obfuscated mode to bypass VPN blocking.
- Switch to a different protocol: OpenVPN with obfuscation or WireGuard with obfuscation can be more resilient on restrictive networks.
- Use a stable, known port: UDP is often blocked less than TCP on restrictive networks, but some networks favor TCP for reliability—test both if possible.
- Split tunneling: If allowed, route only essential apps through the VPN to maintain speed on the rest of your traffic.
Section: Device and app optimization
- Keep Surfshark app updated: Ensure you’re on the latest version for speed improvements and bug fixes.
- Disable VPN on startup: If you don’t need VPN all the time, turning it on only when needed reduces background load.
- Clear app cache and data: If the Surfshark app is behaving oddly, a clean reinstall can help.
- Check device performance: A fast device handles VPN encryption more efficiently; on older devices, performance may be limited.
- Router firmware updates: Outdated firmware can limit VPN throughput; keep router firmware current.
Section: Network health and external factors How many nordvpn users are there unpacking the numbers and why it matters
- Internet plan speed: Confirm your baseline speed matches what you’re paying for. If not, contact your ISP.
- Peak usage times: Late evenings can be congested; test at different times to gauge consistent performance.
- Local interference: Other devices smart speakers, smart home hubs can create network contention on the same Wi-Fi channel.
- QoS settings: If your router supports QoS, prioritize VPN traffic or streaming apps to reduce buffering.
Section: Advanced troubleshooting and tests you can run
- Compare speeds with and without VPN across multiple servers in a table.
- Run traceroutes with VPN enabled to identify where latency spikes occur.
- Use a consistent test method: same time of day, same server choice, same device, and same app usage scenario for reliability.
- Check for DNS leaks: Ensure the VPNDNS is resolving queries only through the VPN tunnel.
- Inspect MTU size: If you’re seeing fragmentation, test different MTU values to optimize packet size.
Section: Monitoring and ongoing improvements
- Keep an eye on server status: Surfshark provides status pages or in-app indicators for server load.
- Rotate servers regularly: If you notice a drop in speed on one server, switch to another.
- Schedule periodic re-tests: Do a quick speed check weekly to catch trends or changes in performance.
- Document your results: A simple worksheet of server, protocol, latency, download/upload speeds helps you pick the best combo over time.
Section: Real-world tips and practical heuristics
- If you’re gaming: Choose low-latency, nearby servers with WireGuard enabled if possible.
- If you’re downloading large files: You might tolerate higher latency for improved throughput; test different servers and protocols to find the best balance.
- If you’re on a shared network: Off-peak times can yield faster speeds; test early mornings or late nights for potential improvements.
- If you’re using multiple VPNs or a multi-VPN setup: Disable competing VPNs to eliminate double encryption overhead.
Tables: speed test example illustrative
- Baseline no VPN: 150 Mbps download, 20 Mbps upload, 15 ms ping
- Surfshark WireGuard to nearby server: 120 Mbps download, 18 Mbps upload, 22 ms ping
- Surfshark OpenVPN UDP to near server: 90 Mbps download, 14 Mbps upload, 28 ms ping
- Surfshark OpenVPN TCP to near server: 70 Mbps download, 12 Mbps upload, 45 ms ping
- Surfshark WireGuard to far server: 70 Mbps download, 10 Mbps upload, 60 ms ping
Note: Your real results will vary by device, network, and location.
