Hello jack jai,

Thank you for writing.

The performance considerations for RadCarousel that you have to keep in mind are the following:

Size of the images that you are using in the carousel items. Avoid large images, because they have a performance penalty on the animations. Here is a blog post where the author seems to have implemented a method that shows exactly how to manipulate large images:
http://blog.justinholton.com/post/Create-a-Scaled-GDI-Thumbnail-(Constrain-Proportions).aspx
Item Reflections are calculated dynamically, and impact performance. If you are using reflections, try setting the ItemReflectionPercentage property to a lower value (even zero) to see whether this helps.
Transparent background. Consider turning off transparency (if your carousel is set with a transparent background) by setting a Carousel background image that mixes well with the form background.A very good example that demonstrates the RadCarousel with a well-mixed background is located in the Quck Start Framework under RadCarousel -> Music Library.
Number of items that you have in the carousel. Generally speaking, having more than 10 items will slow it down, especially if some of the above items are true.

If the above tips do not help, we will highly appreciate it if you send us more information about your project and even send us a sample project so that we can review it.

In order to show text under images please, turn on Carousels Item's Display Style to ImageAndText:

((RadButtonElement)this.carouselItem1).DisplayStyle = DisplayStyle.ImageAndText

You can find more information on the RadCarousel properties in the documentation.

Contact me again if you have any further questions.
