VPN services offer many different benefits like security, anonymity, data protection, internet freedom, network speed, unlimited bandwidth and many more. The service is useful in many different ways and just like that, it also has an adverse impact on the performance of your devices. It might be a laptop, PC, smartphone, tablet or gaming console, the impact is still there across the board. Device processing capacity and various other factors do take a beating. Impact on any of your devices will be based on VPN software quality, encryption algorithm and the type of processing unit.
Device CPU
Central Processing Unit or the performance unit of your device has a role to play in determining the impact of VPN on devices. If your processor is lightning fast then the impact of the VPN on your server will be meager but otherwise you will have to face the heat. If your computer is running an i7, i5 or even an i3 processor, the impact of VPN on your PC or laptop will be lower. Experience of the user will not be affected in any means. Smartphones and tablets with a quad core or dual core processor will also be capable of handling a VPN client. Internet traffic will also play a role because if you are an extensive internet user, then your processor will automatically run slow.
Battery draining is one of the main adverse effects that VPN has on your smartphone or tablet especially when you are an extensive internet user. If you are a heavy internet user then it would be better if you could use any of the modern day smartphones or tablets which come loaded with the ability to handle the load that a VPN imparts.
VPN software quality
Quality of your VPN software is also very important in determining the adverse impact that a user may experience. If you are using well developed VPN client software then you will face very little to no adverse impacts because of its sheer quality and performance. Your system resource usage will be limited when the software quality is good. Frequent crashes and bugs may cause problems quite often if the software is not well developed to handle the performance metrics.
Encryption algorithm
An encrypted tunnel based protocol network provided by a VPN delivers unparalleled security and anonymity. Your VPN service provider will provide multiple encryption and security options based on which, the speed and quality of the internet network will differ. If you are looking to obtain a much high level of security using a SSTP/L2TP/IPSec protocol with a 256-bit AES encryption or more, you have to get used to a slow performing device. Your processor or CPU will be adversely affected if you choose a high security network.
Just for the sake of speed or performance do not select a low rated VPN encryption algorithm because it may not affect your device performance but at the same time, it will provide you with a low secure internet connection. OpenVPN is one of the latest and most sophisticated VPN protocols and this does not affect your internet connection by any means. We would highly recommend you to choose OpenVPN protocol. These are the three factors that determine the impact of VPN on devices.
