X- Window System is the graphics framework for Unix/Linux desktops. MicroXwin is our next generation graphics implementation that is used in VOLKSPC OS. MicroXwin’s custom Xlib library sends graphics commands directly to the graphics driver which handles all the drawing. Unlike X-Windows, MicroXwin is not a client-server implementation. All rendering is direct and done by the client.
MicroXwin is fast, stable and has low-latency. This is a clip of MicroXwin running on a Raspberry Pi.
The clip clearly shows that lag on window movement is much less and gtkperf is 66% faster.
This is a clip of MicroXwin running on Cubieboard2.
With 2 instances of gtkperf running we can see that MicroXwin is about 2X faster than X-Windows.
