I am a person who wants to test everything under the hood, so under the hood of this app I went and found Dalvik VM Heap, and so did some research on this just to see what it does. Without going into details, it can enhance performance, but I suggest reading about it, for everything has pros and cons. I also found out that my animated weather on beautiful widget stopped working, and researching this problem I found that I had tweaked the resolution of my Droid through this app, which will affect the animation. I set the resolution to stock setting and I have my animation back. Look at everything the app offers and research it before executing anything.
