What to do when you have speed problems?

When using a VPN connection, all data is divided into packets before being sent. These data packets are then encrypted with AES-256 bit. This is a complex and computationally intensive step. After the encryption, more control information is set before the data (Header), so due to additional information every packet is bigger as it originally was. This so-called “Overhead” is proportionally bigger, the more small packages are sent, since the control information have a fixed size regardless of the size of the original packets. For example, at CyberGhost (via OpenVPN) this takes approximately 50 bytes per packet (it varies depending on the setting for encryption, authentication etc.).
