Quick wins to boost Surfshark speed
- Switch servers: If one server is slow, connect to a nearby city with good route reliability. Aim for servers within 100–200 miles if possible.
- Change protocol: Try IKEv2 or WireGuard WireGuard tends to be faster on most networks before fallback to OpenVPN.
- Disable unused features: Clean up features you don’t use MACE, CleanWeb, MultiHop if they’re not needed for your use case.
- Reboot and reconnect: A quick router and device restart can clear stale connections and improve handshake performance.
- Check background apps: Close apps that are bandwidth-hungry or not VPN-related, like cloud backups or large downloads.
- Use split tunneling where available: Send only essential apps through VPN to reduce overall load.
Choosing the right server
- Proximity matters: Servers closer to you usually offer lower latency and higher speeds.
- Load matters: Some servers experience higher user load. Surfshark shows server load indicators—prefer servers with lower load.
- Use latency tests: Ping tests to the server can help you estimate responsiveness before full VPN use.
- Purpose-built servers: For streaming, gaming, or VoIP, some servers are optimized for speed and lower jitter; check Surfshark’s recommended lists for your region.
Practical server selection checklist
- Location: Pick the closest region with a strong uptime history.
- Load: Choose servers with low current load often displayed in the app.
- Purpose: If streaming, try servers labeled for streaming; if gaming, look for low-ping options.
- Time of day: Try different servers at peak vs off-peak hours to compare consistency.
Protocol and encryption settings
- WireGuard first: In most cases, WireGuard offers best performance with Surfshark. If you’re on a flaky connection, try OpenVPN UDP as a fallback.
- Adjust MTU if needed: If you see packet fragmentation or broken connections, adjusting MTU by a small amount e.g., 1420 can help.
- Enable VPN kill switch: Ensure the kill switch is on to prevent leak attempts that could cause retries and slowdowns in unstable networks.
- Disable obfuscation unless needed: If you don’t live in a country that blocks VPNs, turning off obfuscation can improve speed.
- IPv6: If your network supports IPv6 natively, test with IPv6 on and off. Sometimes disabling IPv6 avoids dual-stack overhead.
Device-specific optimizations
- Windows/macOS:
- Ensure the latest Surfshark app is installed.
- Disable power-saving settings that throttle network adapters.
- Use Ethernet over Wi-Fi when possible for stable throughput, then test VPN speeds.
- iOS/Android:
- Use the latest OS version and Surfshark app.
- Test both cellular and Wi-Fi; cellular networks can be inconsistent, affecting VPN speed.
- Allow background data for Surfshark to keep a steady tunnel.
- Desktop vs mobile:
- Desktop devices typically have more stable connection options—start there and iterate on mobile if you need mobile VPN access.
Router-level tweaks
- If you’re routing all traffic through Surfshark, a router-level setup can help but may require more tweaks:
- Use a router with a strong CPU to handle VPN encryption efficiently.
- Enable WireGuard on the router if possible; some devices support WireGuard natively or via custom firmware.
- Split tunneling at the router level when supported, so only essential devices go through VPN.
- Check MTU and TCP MSS values on the router to prevent fragmentation and improve throughput.
- Reboot regularly: A periodic reboot of the router helps keep routing tables fresh and avoid stale sessions that slow down traffic.
Advanced network optimizations
- Test different DNS options: Surfshark uses its own DNS, but you can try a fast external DNS like a reputable public DNS to see if it reduces resolution delays.
- QoS settings: If your router supports QoS, prioritize VPN traffic or latency-sensitive apps gaming, VoIP to reduce jitter.
- Check for IP leaks: Run a privacy check to ensure your VPN isn’t leaking and causing extra overhead from fallback routes.
- Disable IPv6 on VPN interface if you don’t need it: In some networks, IPv6 can complicate routing and cause slower fallback paths.
- Keep firmware updated: Router firmware updates can include performance and security improvements that indirectly boost VPN speed.
Real-world speed benchmarks and data
- Typical results: On a good home connection 100–200 Mbps plan, users often report 60–90% of base speed when connected to a nearby WireGuard server, depending on the destination. A poor connection may see 20–40% depending on distance and ISP routing.
- Streaming tests: 4K streaming through Surfshark on a nearby server can sustain high bitrates with minimal buffering if the server is not overloaded.
- Gaming latency: Ping can be in the 15–40 ms range with a nearby server; however, VPN adds some overhead, so expect higher pings than a direct connection.
- Mobile data scenarios: Cellular networks introduce variability; you’ll typically see more fluctuation but can still achieve stable streaming with the right server and protocol.
Note: These benchmarks vary by location, network, time of day, and Surfshark server load. Running your own tests using Ookla Speedtest or Fast.com while connected to Surfshark gives the most accurate picture of your specific setup.
How to test speeds and compare results like a pro
- Baseline test: Run a speed test without the VPN to establish your baseline.
- VPN test: Connect to Surfshark and run the same speed test to measure the delta.
- Repeat after changes: After each tweak server change, protocol switch, DNS tweak, re-test to quantify impact.
- Test multiple servers: Try 3–5 nearby servers to identify the best performer.
- Track latency separately: For real-time use gaming/VoIP, pay attention to ping as well as download/upload speeds.
- Document results: Keep a simple log of server, protocol, time of day, and results to identify patterns over days or weeks.
Common speed killers and how to avoid them
- Overloaded servers: Pick servers with lower load indicators and avoid peak times.
- Poor routing: Some ISPs route through congested paths; switching VPN servers helps.
- Thick encryption overhead: If you don’t need the strongest encryption for a task, switch to a lighter-protocol to speed up performance.
- Background downloads: Pause automatic updates or backups while VPN is active.
-DNS resolution delays: Use a fast DNS provider or Surfshark DNS if you don’t mind external resolution. - Wireless interference: If you’re on Wi-Fi, reduce interference by moving closer to the router, changing channels, or switching to 5 GHz.
When to contact support
- Consistent slowdowns across multiple servers and devices.
- Recurrent disconnects or handshake failures.
- Specific error messages in Surfshark app logs.
- After a major network change new router, ISP changes, or OS updates.
- If you need custom router setup guidance or advanced configuration help.
