UIPanel displaying 600+ UIWidgets scrolling is very slow

[Denko]

Is there a way to optimize this? Right now we're displaying 600+ images and whenever we scroll, the dragging/scroll bar move very very sluggishly, in very slow increments. Is there a way to make this more fluid than what it is? FWIW when we display 200-300 images everything scrolls just fine.

I have attached the prefab and the panel's inspector view in Unity so you guys can see all of the settings that we currently have set.

Sorry guys, here is the second image of the UIPanel used to clip the images.

Too many widgets. If you want it to run faster, reduce the amount of stuff you have in the scroll view.
