you can write me a pm or an email to the address which is mentioned in the example script.

did you play around with the demo? the example model should give an impression about performance. you could compare the frame rate with and without the light map and maybe with more copies of the model in the level.

(but keep in mind that for performance it probably would be more ideal to use several <~5000 polygon models instead of big models like the 20000 polygon one in the example.)
