Why Surfshark might feel slow common causes How Many Devices Can I Use With Surfshark VPN An Unlimited Connection Guide For Your Digital Life

Server distance: The farther you are from a Surfshark server, the more latency you’ll experience.
Server load: If a server is crowded, speeds drop. This is especially true during peak hours.
Protocol and encryption: Some protocols trade speed for security. Default WireGuard is usually fast, but others like OpenVPN can slow things down.
Local network issues: Wi-Fi interference, ISP throttling, or router limitations can masquerade as VPN slowness.
Device performance: Older devices or apps running in the background can impact VPN speed.
DNS and IP leaks: Misconfigured DNS can cause extra hops and slower connections.
Streaming and anti-VPN blocks: Some services detect VPNs and throttle or block traffic.

Quick-speed audit: get a baseline

Run a 3–5 minute speed test on a non-VPN connection to establish baseline speeds for download, upload, and ping.
Run a 3–5 minute speed test with Surfshark connected to a nearby server using WireGuard default recommended and record numbers.
Compare results: note the delta. If you see a big drop, focus on the server, protocol, and device tips below.

Top fixes that move the needle fast

Switch to the closest server

In Surfshark, open the app, choose a server in your city or a nearby metro. The goal is to reduce latency, not just get a “different country.”
Test 2–3 nearby servers and pick the fastest one. You’ll often see a win of 20–60% in latency.

Use the WireGuard protocol or equivalent fast protocol

WireGuard is lightweight and fast. In Surfshark, go to Settings > Protocol and select WireGuard or WireGuard IPv6 if available.
If you’re on a network that blocks WireGuard, try OpenVPN UDP as a fallback, but expect some speed trade-off.

Optimize your device settings

Close bandwidth-heavy apps while testing cloud backups, streaming downloads, large updates.
Disable unnecessary VPN auto-connects and background processes on mobile devices.
If you’re on a laptop, ensure no other VPNs are active or conflicting.

Disable IPv6 for VPN connections

Some networks route IPv6 traffic oddly when the VPN is active, causing slower performance. In Surfshark settings, turn off IPv6 if you don’t need it.

Flush DNS and reset network stack

On Windows: open Command Prompt as admin and run:
- ipconfig /flushdns
- netsh int ip reset
- netsh winsock reset
On macOS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
Reconnect Surfshark and test speeds again.

Use a reputable DNS on the VPN

Surfshark offers built-in DNS, but you can also set a trusted third-party DNS e.g., 1.1.1.1 or 8.8.8.8 in your device settings while connected to Surfshark.
This reduces DNS lookup delays and can improve page load times.

Optimize your router and home network

Reboot your router and modem to refresh connections.
If you’re using Wi-Fi, place your router in a central location, away from walls and interference.
Consider a 5 GHz band connection for devices that support it, or upgrade to a Wi-Fi 6 router for better VPN handling.
Enable QoS on the router for VPN traffic if supported.

Check for throttling and ISP limitations

Some ISPs throttle VPN traffic. If you suspect this, test with a mobile hotspot cellular data to compare results.
If the mobile test shows better speeds, you might be hitting ISP VPN throttling on your home network.

Check for background downloads or updates

Pause or schedule large downloads/upates for times you’re not using the VPN for important tasks.

Reinstall Surfshark

If the app seems buggy or consistently slow, reinstall Surfshark to reset its state and clear potential corruption.

Speed-boost tips for specific use cases

Streaming Netflix, YouTube, Hulu
- Connect to a server in the same region as the content e.g., US server for US streaming libraries.
- Use the WireGuard protocol for the lowest buffering, especially on mid-range connections.
- Enable the “Smart DNS” feature if available to optimize streaming routes.
Gaming Is Your VPN a Smart Business Expense Lets Talk Taxes: A Comprehensive Guide for 2026
- Use the closest server to your game server to minimize ping.
- Disable enabling features that add extra encryption overhead if you’re a competitive gamer, but only as a last resort and with consideration for security.
- Test different servers during off-peak hours to find the least congested option.
Browsing and general use
- Keep the protocol on WireGuard and the VPN auto-connect off unless you’re using the VPN regularly.
- Use a fast DNS setting and ensure IPv6 is disabled if you’re not using it.
Public Wi-Fi safety
- Always use Surfshark on public networks; speed tips are secondary to security here. If you’re on a crowded public network, a closer server can help: try nearby city servers first.

Data and stats to guide you

Users often report a 20–70% latency reduction when switching to nearby WireGuard servers.
Server load can drop speed by 10–40% on peak times; selecting a less crowded server is usually the simplest fix.
In regions with highly restrictive networks, VPN protocols may struggle, and a fallback to OpenVPN UDP can still offer protection with manageable speed.

Advanced troubleshooting deep dive

Test without VPN for baseline speed in the same session to control for time-of-day variation.
If you’re tech-savvy, run a simple ping test to a Surfshark server:
- Windows: ping us-west1.vpn.fastest, then ping us-west1.vpn.fastest -t
- Look for high jitter or packet loss; if present, switch servers.
Check MTU settings if you’re technically inclined. If you see fragmentation issues, lowering MTU by small increments e.g., from 1500 to 1420 can help in some networks.

What to monitor to know you’re improving Can Surfshark VPN Be Shared Absolutely and Its One of Its Standout Features: Comprehensive Guide for VPN Enthusiasts

Latency ping under 40–60 ms on nearby servers for smooth gaming.
Consistent download speeds above 50–70% of your non-VPN baseline on streaming tasks.
Stable connection with no frequent disconnects.
Lower buffering times on video streaming after applying recommended settings.

Common mistakes to avoid

Sticking to one far server because it’s “in a different country.”
Forgetting to test after changing a single variable server, protocol, DNS.
Ignoring your device’s power-saving modes and performance throttling.

Security considerations alongside speed

Speed improvements should not come at the cost of encryption strength. WireGuard provides a strong balance of speed and security.
Always use kill switch enabled when you need to ensure your real IP never leaks if the VPN disconnects.
Verify DNS leaks are not happening by performing a DNS leak test while connected to Surfshark.

Comparative tips: Surfshark vs. alternative VPNs

WireGuard typically offers the best speed-to-security ratio across most networks.
OpenVPN UDP is a solid fallback on networks where WireGuard is blocked but can be slower.
If you’re evaluating alternatives for speed, test a couple of servers with both protocols to see what yields the best results in your environment.

Maintenance and ongoing optimization

Re-run speed tests weekly, especially after server updates or network changes in your area.
Keep the Surfshark app updated to access the latest performance improvements.
Clean up devices that constantly run updates or background syncing while you’re trying to improve VPN speed.

Frequently Asked Questions

Table of Contents

Why is Surfshark slower on Wi-Fi but fine on mobile data?

On Wi-Fi, you’re sharing bandwidth with many devices and potential interference, which can increase latency and reduce VPN performance. Mobile data often has less congestion on a per-user basis, leading to better performance when using Surfshark.

Does turning off IPv6 really speed things up?

Yes, in many cases IPv6 traffic can be routed inefficiently when a VPN is active. If you don’t rely on IPv6, turning it off can reduce extra hops and speed up connections.

Is WireGuard always the fastest option?

Generally yes, but some networks block WireGuard or have routing quirks. In those cases, OpenVPN UDP is a solid fallback with decent speed and strong encryption. The Ultimate VPN Guide for Your ARR Stack Sonarr Radarr More: Protect, Stream, and Automate with Confidence

How often should I switch servers for best performance?

If you notice slowdowns, try 2–3 nearby servers and compare. If one consistently outperforms others, stick with it for a while before reassessing during peak times.

Can Surfshark speed up streaming in 4K?

Often, yes. Use a nearby server, enable WireGuard, and ensure your device supports 4K streaming. If your ISP throttles streaming traffic, try different servers or enable Smart DNS features if available.

Should I disable kill switch to improve speed?

Not for everyday use. The kill switch protects you if the VPN drops. Only disable it temporarily for troubleshooting or if you’re testing a specific scenario where you need immediate network access.

How do I know if VPN throttling is affecting me?

If you notice a sudden drop in speed only when VPN is on, try different servers, test without VPN, and test on a mobile hotspot. If mobile shows much better speeds, throttling could be a factor on your home network.

Is it worth changing DNS settings for speed?

Yes, a faster, more reliable DNS can shave off lookup times and improve page load speeds. Use a trusted DNS or Surfshark’s built-in DNS for best results. How to Connect All Your Devices to NordVPN Even More Than You Think

How do I measure the improvement after changes?

Record baseline speeds non-VPN and VPN engaged and re-test after each change. Compare latency, download, and upload speeds to quantify improvement.

What’s the best setup for gaming with Surfshark?

Close to your game server for lowest latency, WireGuard protocol, and a stable connection. Disable features that add overhead only if you’re comfortable with the trade-off for speed.
