Private Internet Access or PIA is one of the fastest VPNs available today. Assuming your default internet connection is a 100mbps, you’ll get a max download speed of 81mbps on local servers. That’s a speed reduction of merely 9%! However, users are only able to achieve this kind of speed by downgrading the encryption standard from AES-256 to the less data-consuming AES-128. While the latter is secure, it should be fine to switch to that standard as long as you’re on a trusted server.
