Although we continuously optimise our servers, it is possible that there is a small delay in the internet connection with the VPN on. This is because the VPN must encrypt all data, so that it is and remains truly private. But, this process also costs data in the connection, so it is possible to experience some delay while surfing the internet. However, this shouldn't be so much that it bothers you. Is that the case? Then you can try if it works better with another server or another protocol.
