How VPN Works

2) The VPN Protocols, Different protocols can be used to establish a VPN connection. Some of the more popular ones include OpenVPN (over UDP or TCP), SSTP, PPTP and L2TP/IPSec. Everything else being equal, each protocol can result in a significantly different VPN speed. For example, using OpenVPN over UDP typically results in a faster connection than OpenVPN over TCP.

In this article, I will look at several factors that can influence the speed of a VPN, and how they can be mitigated.

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.

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.

1) The VPN Server Location. Typically, establishing a connection with a VPN server closer to your location will result in better speed. This is because the complexity of Internet traffic goes up as the distance between you and the VPN server increases. The more complex the traffic, and the greater the distance data has to travel, the slower the VPN speed.
