Hi Giuseppe,

The loading time of the page and the parsing/rendering of Telerik AJAX controls javascript and html can vary depending on the features and number of components you load at once.

To improve the performance in your case, I suggest you replace RadTextBox with standard MS TextBox and use RadInputManager control. The main performance benefit which RadInputManager control has is related to the loading time of a large number of input controls on the page. More information about RadInputManager is available in the following articles:
RadInputManager Performance
Dynamic Input Filter Settings

Additional useful techniques for performance optimizations you can find in th e the support resources below:
