Connecting to a VPN may slow your internet connection since your data has to travel a greater distance to reach its destination. When you use a VPN, your traffic is both encrypted and rerouted through a remote server, which adds distance and encryption overhead that affects speed.
Summary: How to Enhance Your VPN Speed
- Select a VPN server that is geographically close to you.
- Change servers if your current one is experiencing slow performance or congestion.
- Utilize fast protocols like WireGuard or OpenVPN.
- Activate split tunneling to send only necessary traffic through the VPN.
- Consider switching to a public DNS server for possible speed gains.
What Causes a VPN to Slow Down Your Internet?
A VPN encrypts and reroutes your data through a remote server, which increases the travel distance and introduces encryption overhead, slowing down your connection. The extent of the slowdown depends on the VPN provider, the protocol used, and the server location.
How Much Can a VPN Diminish Your Speed?
The decrease in speed varies based on the distance to the server, its load, and the infrastructure of the VPN. Servers that are nearby generally lead to minor speed reductions, while far-off servers tend to result in more significant slowdowns. Free VPNs are often more congested and slower due to limited infrastructure.
Factors Influencing VPN Speeds
1. VPN Protocol
Different protocols affect speed differently due to the encryption overhead involved. WireGuard and IKEv2 provide faster speeds, whereas OpenVPN (particularly TCP) might slow your connection more.
2. Server Location
Servers that are closer to you offer quicker connections, while those farther away can add latency. Opting for a server located near you helps minimize speed loss.
3. Server Load
Servers that are overloaded with users can slow down connections. Choosing servers that are less congested can enhance speed.
4. Quality of the VPN Service
The speed of a VPN relies on the provider’s network and infrastructure. Quality services invest in improved networks, leading to better speeds.
Ways to Boost VPN Speed
- Opt for Nearby Servers: Connect to servers that are close to your location to achieve faster speeds.
- Change Servers: Move to servers with less traffic in the same area.
- Utilize Fast Protocols: Switch to WireGuard or OpenVPN for enhanced speed and security.
- Activate Split Tunneling: Only send essential traffic through the VPN to lighten the load.
- Install VPN Software Directly: Use the VPN app on your device for improved performance as opposed to router installations.
- Alter DNS Server: Change to a public DNS server if the VPN's DNS is slow.
- Shut Down Background Applications: Close unnecessary apps to free up bandwidth.
- Use Wired Connections: Ethernet connections are generally faster and more reliable than Wi-Fi.
Can a VPN Increase Your Internet Speed?
In certain situations, a VPN can circumvent ISP throttling, potentially increasing your speed for certain tasks like streaming and P2P sharing by keeping your ISP from monitoring and limiting your traffic.
How to Assess VPN Speed
- Conduct a speed test without the VPN to establish baseline speeds.
- Connect to your chosen VPN server and run the test again.
- Compare the results to evaluate the VPN's effect on your connection speed.
Conclusion
Although VPNs can reduce your internet speed due to encryption and rerouting, selecting the right servers, protocols, and settings can lessen the impact. In some cases, a VPN may even enhance speeds by evading ISP throttling.
