VPN overhead refers to the extra data that is added to your original data packets when using a Virtual Private Network (VPN). This added data is necessary for the VPN to function, enabling encryption and routing of your traffic through the VPN server. The overhead typically includes the VPN protocol's own headers and encryption.

This overhead can impact your internet connection speed and bandwidth. When you send data through a VPN, each packet is encapsulated within another packet. This process adds extra bytes to the original data. For example, protocols like OpenVPN or L2TP/IPsec add their own headers for security and routing information.

The amount of overhead can vary depending on the VPN protocol used, the encryption strength, and the specific VPN client and server configurations. Stronger encryption generally leads to slightly more overhead. While modern internet connections are often fast enough to make this overhead negligible for everyday browsing, it can be more noticeable during activities that require high bandwidth, such as large file downloads, streaming high-definition video, or online gaming, where even small reductions in speed can be impactful.

Users who experience a significant performance drop may investigate different VPN protocols or adjust settings to find a balance between security and speed. Some VPNs offer different protocol options, allowing users to choose one that might have less overhead.
