Using a Virtual Private Network (VPN) is a great way to protect your data and keep your online activities private. But, it can also slow down your internet connection. This is because a VPN encrypts your data, making it unreadable by anyone who can intercept it. This encryption process takes time, which can lead to slower upload and download speeds.
When you use a VPN, your traffic is routed through its own servers. This acts as an intermediary between you and the website you want to visit. This can cause latency, which can slow down your connection. The OpenVPN protocol is the most commonly used encryption protocol and is considered secure and reliable.
However, it can also slow down your internet speed. To reduce this, you can switch between TCP (Transmission Control Protocol) or UDP (User Datagram Protocol). NordVPN's quick connect button is useful here because it automatically selects the best server to give you the fastest possible speeds. Depending on your device, platform, and VPN, you might be able to change the type of encryption you use.
For example, NordLynx offers speeds of up to 880 Mbps compared to about 190 Mbps when using OpenVPN. If you're using a VPN to securely view video content, there are ways to make streaming faster. Premium VPNs come with additional security settings and other features that can change the speed of your VPN. The best way to know if your VPN is affecting your Internet connection is to test the speed while downloading a file, with both the VPN turned on and off.
