Understanding why Surfshark might feel slow

Distance to server: the farther away, the higher latency.
Server load: overcrowded servers slow down everything.
Protocol choice: some protocols are faster on certain networks; WireGuard tends to be fast, but not always the best on every device.
Local network factors: Wi-Fi interference, ISP throttling, or router config can cap VPN performance.
Device constraints: older devices or simultaneous apps can bottleneck speed.
Data center routing: sometimes Surfshark’s routes aren’t optimal for your destination.

Quick-win fixes you can apply today

1 Run a baseline speed test

Before you connect Surfshark, run a speed test to get your natural speed without VPN.
Then run a test with Surfshark connected to a nearby server same device, same time of day.
Compare Mbps and latency ms. Look for a noticeable drop; if it’s minimal, the problem is likely server-side or routing.

2 Switch servers and why distance matters

Pick a server in your country or a nearby country first. If you need to access content in another region, test a few different nearby options before giving up.
Avoid overcrowded servers: Surfshark often shows server load indicators; choose ones with lower load for best results.
Try Load-Balanced or Rotating servers if you’re streaming or gaming; they can offer smoother performance under heavy traffic.

3 Change the protocol

WireGuard recommended for speed: usually fastest, low latency.
IKEv2: reliable and good on mobile networks.
OpenVPN UDP: reliable but sometimes slower on mobile or poor networks.
If you’re on a slow connection: start with WireGuard, then test IKEv2 if you need stability on a flaky network.
Disable any extra encrypted tunneling options if you’re not leveraging them for privacy.

4 Enable or disable features based on your use-case

No Borders: can help bypass restrictions but adds overhead; disable if not required.
CleanWeb: blocks ads and trackers; might add a tiny bit of overhead; turn off for a test.
MultiHop: can add latency; use for extra privacy, not for speed tests.

5 Optimize your router and device settings

Router: update firmware, enable VPN passthrough, and choose a strong Wi-Fi channel to reduce interference.
MTU settings: default MTU 1500 is usually fine, but some networks benefit from lowering to 1420–1460. If you notice unstable connections, adjust MTU gradually e.g., 1420, 1400 and test.
Ethernet over Wi-Fi: whenever possible, use a wired connection to reduce packet loss and interference.
Background apps: close apps that sync heavily cloud backups, streaming services, large software updates that could consume bandwidth while VPN is on.
DNS: switch to a fast DNS like 1.1.1.1 or 9.9.9.9 within Surfshark or device-level DNS settings.

6 Check for ISP throttling signals

If you notice slow speeds only when you’re using certain services video calls, streaming, you might be dealing with ISP quality-of-service controls.
Using a VPN helps bypass some throttling, but the effect varies by ISP and region. If you suspect throttling, test at different times of day and with various servers.

7 Update and reinstall

Ensure Surfshark app is up to date. New versions often fix speed bugs and improve protocol handling.
If issues persist, reinstall Surfshark to reset settings that could be causing slowdowns.

Data-backed optimization: what the numbers say

In multiple independent tests, WireGuard over Surfshark can provide 20–50% higher throughput on average compared to OpenVPN UDP, with latency reductions of 10–30 ms on short-distance connections.
Mobile vs. desktop performance can vary; iOS and Android tend to perform well with IKEv2 and WireGuard, while desktop often benefits from WireGuard as default.
Server load balance matters: when a server is 80% loaded, throughput can drop significantly; aim for servers under 50–60% load during peak hours.

Practical testing plan step-by-step

Take a 15-minute baseline on your regular connection without VPN.
Connect to a nearby Surfshark server with WireGuard; record speed and latency.
Move to 3–5 additional nearby servers and compare results.
Try IKEv2 on the same servers to compare stability vs. speed.
Turn off No Borders and CleanWeb; re-test if you’re streaming.
Test with and without Ethernet if possible.
Try MTU adjustments 1420, 1400 if you encounter packet fragmentation or instability.
Re-check after router firmware update and any Surfshark app updates.
Keep a simple log of the best-performing server and protocol for future use.

Use-case specific tips

For diabetes-life.org readers doing remote research or telehealth sessions:
- Prioritize stable low-latency connections to minimize call dropouts.
- Avoid servers far away from your location to reduce jitter during video conferences.
- Use CleanWeb if you’re on public Wi-Fi to reduce ad noise that can waste bandwidth.

Real-world server recommendation examples hypothetical data

If you’re in New York, you might test:
- Surfshark NYC server WireGuard, load ~40%
- Surfshark NJ server WireGuard, load ~30%
- Surfshark LA server IKEv2, load ~50%
If you’re abroad, try:
- London, Paris, Frankfurt near-term options WireGuard before long-haul picks.

Security and privacy considerations when fixing slow VPN

Always use a secure protocol suitable for your device; avoid insecure defaults.
Don’t disable VPN when traveling or using public Wi-Fi if you’re concerned about privacy; the goal is to improve speed without compromising safety.
Regularly update both Surfshark and your device’s security patches.

Platform-specific tips

Windows

Use the Surfshark app’s built-in speed test if available.
Ensure VPN adapter is not blocked by firewall rules; allow Surfshark in Windows Firewall.
Prefer WireGuard as a default, then switch if you need stability.

macOS

Check for system-level DNS leaks by using a reputable DNS test tool.
Use WireGuard for speed; ensure energy saver settings aren’t throttling network activity.

iOS and Android

On mobile networks, prefer IKEv2 or WireGuard for better stability.
Enable “Always-on VPN” if supported to reduce connection dropouts during app switching.

Routers

If you’re routing all traffic, pick a router with strong CPU to handle encryption without becoming a bottleneck.
Use a high-quality Ethernet backhaul to improve reliability when multiple devices are connected.

Optional advanced: testing with third-party speed benchmarks

Use independent tests like Speedtest.net, fast.com, or other reputable benchmarks to cross-check Surfshark performance.
Run tests at different times of day peak vs. off-peak to understand how network congestion affects results.

Troubleshooting quick-reference cheat sheet

If latency is high: switch to a nearby server, try WireGuard, reduce number of hops, disable No Borders.
If throughput is low: test multiple servers, verify your MTU, test Ethernet, check background apps.
If you experience disconnects: switch protocols, ensure your router supports VPN pass-through, reboot devices.
If DNS leaks happen: set Surfshark to use its own DNS resolver or configure a trusted DNS on the device.

Measuring success: what “fast” looks like

Goal: maintain at least 70–90% of your baseline non-VPN speed for typical activities browsing, streaming, light research.
Latency targets: under 60 ms for near-region connections; up to 100–120 ms may still be acceptable for casual use.
Stability: fewer than 1–2 disconnects per hour during normal use.

Best practices for long-term reliability

Schedule periodic server tests: once a month, run a quick speed test to reevaluate server health and load.
Keep a “favorite servers” list based on latest performance data you’ve collected.
Regularly review your device firmware and router settings to stay ahead of performance bottlenecks.

Quick-start checklist recap

Run baseline speed test without VPN.
Test 4–6 Surfshark nearby servers with WireGuard first.
Swap to IKEv2 if WireGuard underperforms on a device.
Adjust MTU if you notice packet loss or instability.
Disable No Borders/CleanWeb temporarily to test impact.
Use Ethernet where possible; optimize router firmware.
Note your best-performing server/protocol combo for future sessions.
