How does TCP acceleration make your VPN performance 6x faster? Alex and Speedify lead developer Kevin explain Transmission Control Protocol (TCP) acceleration and Performance Enhancing Proxy (PEP) technology, now available on OpenWRT, GL.iNET routers, and the Miri X510. For background on the protocol itself, see why TCP still dominates the internet.
We tested with the GL.iNET Beryl AX travel router to show how Speedify’s Router PEP optimizes TCP behavior for best VPN performance, even outpacing WireGuard speeds on a single connection, with double the downstream internet speed. We also look at how Speedify modifies packet sizes, enhances congestion control, and rethinks the End-to-End (E2E) principle of internet protocols to unlock higher throughput, lower latency, and more stable connections across any network environment.
