Buying A VPN Service

4) VPN Server Load and Bandwidth, How powerful the VPN server is will have a significant impact on the speed. Overloaded servers with a bandwidth that cannot keep up with the demand will result in a much slower experience. The client software you use to connect to a VPN service will usually tell you how many IP addresses and how much bandwidth a server has. The higher those numbers, the more powerful the server. Those same clients sometimes even show real-time usage. If the server you are connected to is overloaded, switching to a different one is usually as simple as a couple of mouse clicks.

5) Your Network Setup, Whether your device is on a wired network and physically connected to a router or using WiFi can affect VPN speed. This distinction is especially relevant if you have a fast connection to the outside world. Because a wired connection is often quicker than WiFi, the latter can be a limiting factor. You can try plugging your computer directly into the router to see if there is a speed improvement.

There are no hard set rules as to which protocol will give you the best speed. OpenVPN over UDP is a good default to try. If you find yourself having issues, try switching to a different protocol to see if your VPN speed improves.

3) Encryption Level, Stronger encryption is often more complex and can, as a result, slow down a VPN. A 128-bit encryption will in most cases lead to a faster connection than a 256-bit one. On the downside, lowering encryption strength will make the VPN connection less secure and the transmitted data more vulnerable. So, you can try playing around with the encryption level, but unless you see significant speed improvements with weaker encryption, it is best to stick to the stronger versions.

The speed of a VPN is an important thing to consider, and may also be a determining factor for many people when deciding whether they should use a VPN at all. Speed really does matter when it comes to the Internet. Even if a VPN provides improved online security and can help get around blocked content, if the service is slow, the overall experience will be far from ideal.
