Because a Virtual Private Network encrypts every data packet and redirects traffic through an intermediary server, running a VPN inherently introduces an extra hop in your network (see do you need a VPN for IPTV).
Why a VPN Reduces Throughput and Increases Ping
- Encryption Overhead: Military-grade 256-bit AES encryption adds extra data bytes to each packet header. Furthermore, your streaming stick's processor must decrypt incoming video packets in real time.
- Physical Geographic Distance: If you are streaming in Manchester, connecting to an IPTV server in London via a VPN server in Amsterdam forces your data to make a round trip across the North Sea, increasing latency (ping).
- VPN Server Load: Free or low-quality VPN services overcrowd their servers with thousands of simultaneous users, creating massive bandwidth bottlenecks.
Practical Steps to Minimise VPN Speed Loss
- Choose Nearby Servers: If you are located in the UK, always select a VPN server located in London, Manchester, or the closest UK node. Connecting to an overseas server adds unnecessary latency.
- Use Modern Protocols (WireGuard): Legacy VPN protocols (like OpenVPN) are resource-heavy. Modern protocols like WireGuard (or proprietary variations like NordLynx and Lightway) are lightweight, delivering up to 95% of your baseline broadband speed with minimal CPU strain on streaming devices.
- Avoid Free VPNs: Free VPN services frequently limit bandwidth to 1–2 Mbps, which guarantees constant video buffering. If your connection drops frequently, see VPN connection issues or test with our free 24-hour trial.
