![]() Your average PC processor speed today ranges between 2.4GHz and 3.4Ghz and is equipped with between 4GB to 16GB of Random Access Memory (RAM). That’s why a PC or router needs significant processing power to handle the VPN encryption.Įncryption takes up system resources since you’re basically using the computer to encode and decode raw data. To put this into perspective, let’s look at 256-bit encryption.Ģ56-bit encryption means that every single bot of data that comes out of your computer is encrypted with a ‘key’ that is made up of 256 binaries (1s or 0s). For example, if your computer or router claims to run a quad-core 1.5GHz processor, OpenVPN can only run a single core at that speed. This means that it is very singular in nature, not being able to make use of multi-threaded processors. Unfortunately, developers have not yet made OpenVPN a scalable protocol. It’s more secure than the much outdated PPTP, protocol and for the most part, faster than IPSec. Most VPN users today opt for OpenVPN as it offers the best combination of security and speed that is available. The encryption process is exactly the main thing that makes VPNs on Routers such a bad idea. It also encrypts the data that flows in that tunnel to keep it safe. VPNs do this by helping us create a secure tunnel between our device and a secure server. The main reason most of us look towards VPN is to keep our Internet-related activities private.
