Altering CMS javascript

Hello, We have built an online Content Management System, however because we have used a large number of javascript libraries (which we have listed below), the system is very slow. The system has been written with PHP5, MySQL using the Code Ignitier framework. All the php side works correctly as do the AJAX calls, it is purely the javascript libraries which we believe to be the issue. The HTML controller that is used is TINYMCE. What we require is a javascript expert to strip out/alter the current system to reduce load times and the number of libraries used. We will provide you with the testing area along with the source files. <!-- Prototype --> <script type="text/javascript" src="javascript/scriptaculous/lib/prototype.js"></script> <script type="text/javascript" src="javascript/scriptaculous/lib/ajax_prototype.js"></script> <!-- Ext --> <script type="text/javascript" src="javascript/ext/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="javascript/ext/ext-all-debug.js"></script> <script type="text/javascript" src="javascript/ext/ux/color-picker/color-picker.ux.js"></script> <script type="text/javascript" src="javascript/ext/infobar.js"></script> <script type="text/javascript" src="javascript/ext/ux/UploadForm/Ext.ux.FileUploader.js"></script> <script type="text/javascript" src="javascript/ext/ux/UploadForm/Ext.ux.form.BrowseButton.js"></script> <script type="text/javascript" src="javascript/ext/ux/UploadForm/Ext.ux.UploadPanel.js"></script>
