Effect of VPN on Internet Speed

Utilizing a VPN can result in a slower internet connection since your data must travel a greater distance to reach its endpoint. When you are connected to a VPN, your traffic is encrypted and routed through a remote server, which increases the distance and adds encryption overhead, thereby affecting speed.

Summary: Tips to Enhance Your VPN Speed

Select a VPN server that is close to your actual location.
Change servers if your current one is performing slowly or is congested.
Opt for fast protocols such as WireGuard or OpenVPN.
Activate split tunneling to direct critical traffic through the VPN.
Transition to a public DNS server for possible speed enhancements.

What Causes a VPN to Slow Down Your Internet?

A VPN encrypts and redirects your data through a remote server, which increases the distance your data must travel and adds encryption overhead, resulting in a slower connection. The degree of slowdown depends on factors like the VPN provider, the protocol in use, and the server's location.

How Much Does a VPN Impact Your Speed?

The decrease in speed varies according to the distance to the server, the server load, and the VPN’s infrastructure. Servers that are closer typically lead to minor speed reductions, while those farther away can cause more significant slowdowns. Free VPNs tend to experience greater congestion and slower speeds because of their limited infrastructure.

Elements Influencing VPN Speeds

1. VPN Protocol

Varying protocols affect speed differently due to encryption overhead. WireGuard and IKEv2 tend to offer quicker speeds, whereas OpenVPN (notably TCP) might reduce your connection speed more significantly.

2. Server Location

Connections are faster with servers that are closer, while those that are farther away introduce additional latency. Selecting a server that is near your physical location helps to minimize speed loss.

3. Server Load

Servers that are overloaded with numerous users can slow down connections. Opting for servers with less traffic can enhance speed.

4. VPN Service Quality

The speed of the VPN is contingent upon the quality of the provider’s server network and infrastructure. Premium services typically invest in optimized networks to ensure improved speeds.

Ways to Enhance VPN Speed

Select Nearby Servers: Connect to servers in close proximity to achieve faster speeds.
Change Servers: Switch to servers with lower congestion within the same region.
Utilize Fast Protocols: Make the switch to WireGuard or OpenVPN for the best mix of speed and security.
Enable Split Tunneling: Direct only necessary traffic through the VPN to alleviate the load.
Directly Install VPN Software: Install the VPN application on your device for improved performance over router installations.
Change DNS Server: Opt for a public DNS server if your VPN’s DNS is lagging.
Close Background Applications: Terminate unneeded applications to free up bandwidth.
Use Wired Connections: Ethernet connections typically offer faster and more reliable service than Wi-Fi.

Can a VPN Increase Your Internet Speed?

In certain scenarios, a VPN can help bypass ISP throttling, which may enhance your speed for activities such as streaming and P2P sharing by preventing your ISP from monitoring and limiting your traffic.

How to Evaluate VPN Speed

Perform a speed test without the VPN to establish baseline speeds.
Connect to your chosen VPN server and test once more.
Compare the results to assess the VPN’s effect on your connection speed.

Conclusion

Though VPNs can reduce your internet speed due to encryption and rerouting, selecting the right servers, protocols, and settings can help lessen the impact. In some instances, a VPN may even enhance speeds by circumventing ISP throttling.
