Effect of VPN on Internet Speed

Utilizing a VPN may result in a slower internet connection since your data must travel a longer distance to reach its endpoint. When you're connected to a VPN, your data is encrypted and directed through a remote server, which adds both distance and encryption overhead that affects speed.

Summary: How to Enhance Your VPN Speed

Select a VPN server that is in close proximity to your physical location.
Change servers if the one you're using is slow or busy.
Opt for faster protocols such as WireGuard or OpenVPN.
Activate split tunneling to route critical traffic through the VPN.
Switch to a public DNS server for possible speed enhancements.

What Causes a VPN to Slow Down Your Internet?

A VPN encrypts and routes your data through a remote server, which increases the distance it needs to travel and adds encryption overhead, slowing your connection. The degree of slowdown can vary based on the VPN provider, protocol used, and the location of the server.

How Much Can a VPN Reduce Your Speed?

The reduction in speed depends on the distance to the server, server load, and the infrastructure of the VPN. Servers that are nearer usually result in minimal speed loss, while those that are farther away may lead to more significant slowdowns. Free VPNs are often more congested and suffer from slower speeds due to limited infrastructure.

Factors Influencing VPN Speeds

1. VPN Protocol

2. Server Location

Servers that are closer offer faster connections, while those that are farther away introduce latency. Selecting a server that is near your physical location helps reduce speed loss.

3. Server Load

Servers that are overloaded with users tend to slow down connections. Choosing servers that are less crowded can improve speed.

4. Quality of VPN Service

The speed of a VPN is influenced by the network and infrastructure of the provider. High-quality services typically invest in optimized networks, resulting in better speeds.

Ways to Boost VPN Speed

Select Nearby Servers: Connect to servers that are located close to you for improved speeds.
Change Servers: Switch to servers that are less congested within the same region.
Use Efficient Protocols: Opt for WireGuard or OpenVPN to achieve the best speed and security.
Enable Split Tunneling: Direct only necessary traffic through the VPN to lessen the load.
Install VPN Software Directly: Use the VPN app on your device for superior performance compared to installations on routers.
Alter DNS Server: Change to a public DNS server if the DNS provided by your VPN is slow.
Close Background Applications: Terminate unnecessary apps to free up bandwidth.
Utilize Wired Connections: Ethernet connections generally provide faster and more reliable service than Wi-Fi.

Can a VPN Improve Your Internet Speed?

Sometimes, a VPN can circumvent ISP throttling, which might enhance your speeds for specific tasks like streaming or P2P sharing by preventing your ISP from monitoring and limiting your data.

How to Measure VPN Speed

Conduct a speed test without using the VPN to establish baseline speeds.
Connect to your chosen VPN server and perform another test.
Compare the results to assess the VPN’s effect on your connection speed.

Conclusion

While VPNs can reduce your internet speed due to encryption and rerouting, optimal selection of servers, protocols, and settings can lessen the effect. In some cases, a VPN may even increase speeds by bypassing ISP throttling.
