Salamat poThe main function for using a VPN is to encrypt your data therefore disabling your ISP and any connection outside your VPN Network from reading sensible data unless they know how to decrypt it. It will mostly slow down your connection depending on your VPN servers distance and the overhead of encrypting your data. It can however be used to compressed your data allowing it to virtually have a boost in your connection by only a little but it can not enhance/speed up your own connection.
