Dear all, The DCO driver for Windows (https://github.com/openvpn/ovpn-dco-win) implements OpenVPN data channel in kernel, eliminating context switch and thus noticeably improves performance.
Support for dco-win driver has been merged into openvpn master branch and openvpn installer: x64: https://build.openvpn.net/downloads/snapshots/github-actions/openvpn2/openvpn-master-20220825T0959-104e4ef1-amd64.msi arm64: https://build.openvpn.net/downloads/snapshots/github-actions/openvpn2/openvpn-master-20220825T1004-104e4ef1-arm64.msi (newer snapshots will also do) Please give it a try and share your feedback with us. To enable dco-win driver, add "windows-driver ovpn-dco" to your .ovpn profile. Known limitations: - available for Windows 10 2004 and newer - persist-tun support is coming soon - only aes-128/192/256-gcm ciphers are supported. chacha20-poly1305 is supported starting from Windows 11 - compression is not supported (and should not be used anyway) - server-side support is missing DCO Windows driver will be part of 2.6 release which is coming later this year. -- -Lev _______________________________________________ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
