Frequently Asked Questions
Is it legal to use a VPN?
Yes, VPNs are legal in most countries including the US, UK, Australia, and most of Europe. Some countries restrict VPN use — notably China, Russia, and the UAE. Always check local laws.
What's the best VPN overall in 2026?
NordVPN is our top pick for most users in 2026. It offers the best combination of speed, security, and features at a competitive price. Surfshark is the best value option.
Can a VPN be traced?
A quality no-logs VPN is extremely difficult to trace. VPNs like NordVPN and ExpressVPN have been independently audited and proven not to store activity logs.
How much does a good VPN cost?
A good paid VPN costs $2–7/month on a long-term plan. We recommend avoiding free VPNs — they monetize your data instead of your subscription fee.
Why VPNs Slow Down Your Connection — The Technical Explanation
Every VPN introduces some speed overhead. Understanding why helps you minimize it. There are three sources of latency and throughput reduction when using a VPN:
- Encryption processing overhead: Your device must encrypt every outgoing packet and decrypt every incoming packet. Modern CPUs handle AES-256-GCM encryption very efficiently — on most devices, this adds less than 2ms. WireGuard's ChaCha20 cipher is even faster.
- Routing overhead (the extra hop): Instead of connecting directly to your destination (website, server), your traffic first travels to the VPN server, then to the destination. This extra hop adds latency equal to your distance from the VPN server. Nearby VPN servers (same city/country) add 3–15ms. Distant servers can add 80–200ms.
- Server congestion: VPN servers handle traffic from thousands of simultaneous users. An overloaded server has less bandwidth available per user. Premium VPN providers mitigate this with large server networks and automatic load balancing — budget and free VPNs suffer significantly more from congestion.
VPN Protocol Speed Comparison: WireGuard vs OpenVPN vs IKEv2
The VPN protocol you use has a larger impact on speed than almost any other factor. Here's how the major protocols compare in our 2026 testing on a 1 Gbps fiber connection:
| Protocol | Avg Download | Avg Latency Overhead | Speed Rating | Use Case |
|---|---|---|---|---|
| WireGuard / NordLynx | 780–950 Mbps | +3–8ms | ⭐⭐⭐⭐⭐ Fastest | All use cases — default choice |
| IKEv2/IPSec | 600–750 Mbps | +8–15ms | ⭐⭐⭐⭐ Fast | Mobile (handles reconnects well) |
| OpenVPN UDP | 150–400 Mbps | +10–25ms | ⭐⭐⭐ Moderate | Compatibility, legacy systems |
| OpenVPN TCP | 80–200 Mbps | +20–40ms | ⭐⭐ Slow | Firewall bypass only |
| ExpressVPN Lightway | 700–900 Mbps | +4–10ms | ⭐⭐⭐⭐⭐ Fastest | ExpressVPN exclusive, all uses |
Key takeaway: If your VPN is slow, the first thing to check is your protocol setting. Switching from OpenVPN to WireGuard alone can multiply your speeds 3–5x. Always use WireGuard (or NordLynx/Lightway equivalents) as your default protocol in 2026.

7 Ways to Maximize Your VPN Speed
If your VPN is slower than expected, work through these fixes in order — most users resolve the issue within the first two steps:
- Switch to WireGuard protocol: In your VPN app settings, change the protocol from OpenVPN or auto-select to WireGuard (or NordLynx/Lightway). This single change typically improves speeds 2–5x.
- Connect to a nearby server: Use Quick Connect or filter servers by distance. A server 500 miles away will almost always outperform one 5,000 miles away. If streaming requires a specific country, try multiple servers within that country — server loads vary.
- Use a wired Ethernet connection: Wi-Fi introduces additional latency and bandwidth variability. On a wired Ethernet connection, the VPN protocol's overhead is the primary bottleneck — you'll see significantly more consistent speeds.
- Test during off-peak hours: VPN server load is highest in evenings (US: 7–11 PM). Testing during business hours (9 AM–5 PM) typically shows 20–40% better speeds on the same server.
- Enable split tunneling: If you only need the VPN for specific apps (torrent client, browser), use split tunneling to route only those apps through the VPN. Your other traffic (gaming, video calls) uses the direct connection at full speed.
- Update your VPN app: Older app versions may lack WireGuard support or performance optimizations. Always run the latest version.
- Check your device's hardware: On older devices (CPUs from before 2018), encryption processing can be the bottleneck. AES-NI hardware acceleration (present on all modern x86 CPUs) eliminates this on newer hardware. ARM devices (older Raspberry Pi, Android phones) may see CPU-limited VPN speeds regardless of protocol.
When Can a VPN Actually Improve Your Speed?
While VPNs typically reduce speed, there are specific scenarios where a VPN can genuinely improve your connection performance:
- ISP throttling: Some ISPs deliberately throttle specific types of traffic — video streaming, gaming, torrenting — especially during peak hours. A VPN encrypts your traffic type, preventing the ISP from identifying it to throttle. Users on ISPs that throttle streaming services often see VPN connections providing faster streaming speeds than their unprotected connection.
- Inefficient ISP routing: Your ISP may take a suboptimal path to a destination server. A VPN reroutes through its own infrastructure, which occasionally takes a more direct path. This is most common for international traffic and is why some gaming or streaming users in Southeast Asia see improved speeds with a VPN connecting to nearby regional servers.
- Peering bottlenecks: ISP-to-ISP interconnect points can be congested during peak hours. VPN providers often have direct peering agreements that bypass congested public internet exchange points.
How to Run a Proper VPN Speed Test
Most people run a single speed test and draw conclusions from one data point. Proper VPN speed testing requires a more rigorous approach:
- Test your baseline speed without VPN first, at the same time of day as your VPN tests. This is your reference point.
- Connect to the VPN and run at least 5 tests per server at speedtest.net AND fast.com — the two measure different things (speedtest.net uses nearby servers, fast.com uses Netflix's infrastructure, measuring real-world download performance).
- Test multiple servers — at minimum the closest server to you, one regional server, and one distant server. The closest server should give you 90%+ of your unprotected speed if the VPN is working optimally.
- Test different times of day — morning, afternoon, and evening. Evening congestion on VPN servers is real and significant.
- Use a wired Ethernet connection for testing — Wi-Fi variability obscures VPN-specific overhead.
- Calculate speed retention percentage: (VPN speed ÷ baseline speed) × 100. Anything above 85% is excellent. Below 60% indicates the VPN is a significant bottleneck.
