Yes, using a VPN and protocol (regardless of the protocol in question) can slow your internet speed to a degree. This is normal because data is encrypted and routed to the VPN server before it reaches its destination. However, WireGuard and NordLynx are faster protocols and all of the VPNs we recommend that use WireGuard offer unlimited bandwidth. As such, you won’t necessarily notice a performance dip and should be able to stream and torrent as normal.
