Both! But compromises must of course be made.

In certain areas easyGUI is more optimized for speed than size - an example is display writing of a single character. This operation must be as fast as possible, as it is used extensively in almost any type of user interface.

An example of code size optimization is storage of font and display data in the target system. Here a very compressed format is used, which at the same time does not require time-consuming unpacking routines.
