Performance

Graphical toolkits vary in many ways and each has various pros and cons in their design and implementation. This page aims to provide some context for different toolkits in a reasonably subjective manner. Of course we can't measure developer enjoyment or ease of learning - but we can measure runtime statistics :).

The application we will use is a simple Game of Life simulation. To keep things as equal as possible the board will be loaded with 50 * 50 cells each approximately 10 pixels in size, the game should run at 3 frames per second.
