Effects of VPN on Internet Speed

Utilizing a VPN may reduce your internet speed since your data has to travel a longer distance to reach its endpoint. When you're connected to a VPN, your online traffic is encrypted and sent through a remote server, which adds distance and encryption overhead that can affect speed.

Summary: Tips for Enhancing Your VPN Speed

Select a VPN server that is close to your actual location.
Change servers if your current server is slow or experiencing congestion.
Opt for fast protocols such as WireGuard or OpenVPN.
Activate split tunneling to allow essential traffic to bypass the VPN.
Switch to a public DNS server to potentially improve speed.

What Causes a VPN to Slow Down Your Internet?

A VPN works by encrypting and rerouting your data through a remote server, which can increase the distance your data travels and add encryption overhead, leading to a slower connection. The degree to which this happens depends on factors such as the VPN provider, the protocol used, and the location of the server.

How Much Slower Will a VPN Make Your Connection?

The reduction in speed can vary based on the proximity of the server, its load, and the infrastructure of the VPN. Typically, servers that are closer will have minimal impact on your speed, while those farther away can result in more significant slowdowns. Free VPNs are often more congested and have slower speeds due to their limited infrastructure.

Factors Influencing VPN Speed

1. VPN Protocol

Different VPN protocols can affect speed in varying ways depending on the encryption overhead. Faster protocols like WireGuard and IKEv2 typically offer better speeds, while OpenVPN (particularly in TCP mode) might significantly slow down your connection.

2. Server Location

Servers that are geographically closer tend to provide quicker connections, whereas those located farther away can introduce latency. Selecting a nearby server helps minimize speed loss.

3. Server Load

Servers that are overloaded with numerous users will slow down your connection. Choosing servers that are less congested can lead to improved speed.

4. Quality of the VPN Service

The speed you experience with a VPN also depends on the quality of the provider's server network and infrastructure. High-quality VPN services typically invest in optimized networks, resulting in better performance.

Ways to Enhance VPN Speed

Opt for Nearby Servers: Connect to servers that are closer to you for quicker speeds.
Change Servers: Switch to less congested servers within the same geographic area.
Utilize Fast Protocols: Use WireGuard or OpenVPN for the best balance of speed and security.
Activate Split Tunneling: Route only essential traffic through the VPN to lessen the load.
Directly Install VPN Software: Install the VPN application on your device for improved performance compared to router installations.
Swap DNS Server: Change to a public DNS server if the VPN’s DNS is causing delays.
Close Background Applications: Terminate unnecessary apps to free up bandwidth.
Utilize Wired Connections: Ethernet connections offer faster and more stable performance than Wi-Fi.

Can a VPN Speed Up Your Internet?

In some situations, a VPN can help to get around ISP throttling, which may lead to enhanced speeds for specific activities like streaming or P2P file sharing, as it prevents your ISP from monitoring and restricting your traffic.

Steps to Test VPN Speed

Conduct a speed test without the VPN to establish a baseline.
Connect to your chosen VPN server and run the test again.
Compare the results to assess the VPN's effect on your connection speed.

Conclusion

Although VPNs can cause a decrease in internet speed due to encryption and rerouting, selecting the right servers, protocols, and configurations can help mitigate this impact. In certain instances, a VPN may even enhance speeds by circumventing ISP throttling.
