Hi, My measurements have indicated that there is a performance gain. I have measured the time spent in setPropertyValues and getPropertyValues. The optimized version was 4 times faster in these methods giving an estimated application performance increase of about 3%. Optimizing getPropertyValue and setPropertyValue could give 1.5% more according to our rough calculations.
