Not only creating the translation is done efficiently with an iterative develop and test approach. In the execution all is done to make your translation fast: smart caching mechanism, on the fly compilation to byte code and look-up optimization speeds up the translation as if it was hard-coded. But your translation project is kept easy to change - the magic is under the hood.

The very same mapper code is used in both the visual editor and the final productive flow. You can be assured that you will get what you see.
