TurboVNC 3.0.2 Full Version
TurboVNC is a high-performance, enterprise-quality version of VNC that is built on TightVNC, TigerVNC, and X.org. It makes it easy to connect to a VNC server.
It has a version of Tight encoding that is optimized for 3D applications (VirtualGL), video, and other image-intensive tasks to get the best performance and compression. When used with VirtualGL, TurboVNC is a complete solution for showing 3D applications with interactive performance over the Internet. TigerVNC and libvncserver use TurboVNC’s high-speed encoding methods, and TurboVNC works with any other program that is based on TightVNC.
TurboVNC split off from TightVNC in 2004, and it still has all of TightVNC’s 1.3.x features. However, TurboVNC has many more features and bug fixes than TightVNC, and it compresses 3D and video workloads much better than TightVNC while using only 5–20% of the CPU time. TurboVNC can also be set up to compress 2D workloads as “tightly” as TightVNC if the default settings are changed.
On “modern” hardware, TurboVNC can stream 50+ Megapixels per second over a 100 Megabit per second local area network with almost no quality loss. TurboVNC can stream between 10 and 12 Megapixels per second over a 5 Megabit per second broadband connection, but the image quality is lower but still usable.
TurboVNC Features
Fine-grained control over the quality and amount of chrominance subsampling of JPEG images
On the client side, double buffering is used to reduce tearing in 3D and video applications.
Full-screen and multiple-screen support that can be changed and is flexible
Full support for IPv6
Flow control with updates all the time (greatly improves performance on high-latency connections)
One-time passwords or Unix login credentials can be used for authentication (in addition to standard VNC passwords)
Lists of who can do what (for sharing VNC sessions with only certain users)
Allows global security and authentication policies to be set for a specific server machine
Multithreaded encoding “Lossless refresh” lets a viewer manually or automatically ask for a copy of the current screen image that hasn’t been changed (after a specified number of seconds of inactivity)
High-performance Zero-installation Java viewer that can be deployed with Java Web Start and calls libjpeg-turbo through JNI to get native-level performance.
