About this tag
OpenVPN DCO, or Data Channel Offload, is a kernel-level acceleration feature for OpenVPN connections on Windows. The tag collects coverage of how VPN clients adopt this driver to move packet processing out of user space and into the operating system kernel, which can improve throughput and reduce CPU overhead. Recent discussion centers on PIA 3.8.0 for Windows, which pairs an OpenVPN DCO kernel driver with the WireGuard-NT 1.1 driver and claims substantially faster VPN speeds.
