When you set the encryption level higher than the default settings, it can slow connection speeds significantly or halt them altogether. This occurs because the VPN software must work harder to encrypt and decrypt information as extra layers of encryption are added to the connection.
Private Internet Access (PIA) recommends using the default encryption settings to reduce connection overhead.
