How would using a VPN service help me speed up my Internet connection?

The only way to really make Internet faster is to use a VPN service.
Other applications are just some settings to make your computer save browsing history. And they don't actually do anything except saving files from being downloaded again, which you can simply achieve by using Google Chrome.

So how can you really make your Internet connection faster with VPN?

1-      Routing

Routing is the process of selecting paths in a network along which to send network traffic. Or simply, the path between your computer and the server of the website you are trying to use.  This is in most cases the reason why the Internet is slow. By connecting to a VPN server in strong data center which has very good routing rules, you take the shortest way.
