I am using a RadGrid with the following settings.

    
            <telerik:RadGrid ID="RadGrid1"   
        
            AllowMultiRowSelection="True"   
        
            AllowSorting="True"   
        
            AllowPaging="False"   
        
            AllowNaturalSort ="True"   
        
            AutoGenerateColumns="False"   
        
            AlternatingItemStyle-HorizontalAlign="Center"                                             
        
            BackColor="#ffffff"   
        
            HeaderStyle-HorizontalAlign="Center" 
        
            ItemStyle-HorizontalAlign="Center"   
        
            GridLines="None"   
        
            GroupingEnabled="True"   
        
            Height="370px"   
        
            OnSortCommand="RadGrid1_SortCommand"                                                       OnNeedDataSource="RadGrid1_NeedDataSource"                                                  OnItemDataBound="RadGrid1_ItemDataBound"   
        
            OnItemCommand="RadGrid1_ItemCommand"   
        
            ShowHeader="True"   
        
            ShowGroupPanel="True"   
        
            ShowStatusBar="True"   
        
            ShowFooter="False"   
        
            Skin="MySkin"    
        
            EnableEmbeddedSkins="False"   
        
            Width="98%"   
        
            runat="server">

It is calling a stored procedure that takes 4 seconds to run in PL/SQL developer. When I hook it up to the RadGrid it takes 40 seconds to load 10 X greater. When I use a regular GridView it takes 8 seconds. What is the RadGrid doing to slow the grid creation and how can I make it faster?

There are anywhere from 10-400 rows being returned.

Hello George,

Please review this help topic on how to optimize RadGrid performance.
Below are listed some more suggestions:

server-side: The grid itself cannot cause server-side performance problems related to controls creations and/or render. There might be some possible problems with controls inside grid templates.
data-binding: .NET 3.5 version can handle millions of records and will apply paging, sorting and filtering directly on the data-base server (LinqDataSource) codeless: http://blogs.telerik.com/vladimirenchev/Posts/08-03-10/How_fast_is_your_ASP_NET_DataGrid.aspx?ReturnURL=%2fvladimirenchev%2fposts.aspx%3fYear%3d2008%26Month%3d3
Client-side data-binding approach is also very fast + you will get pure JSON transfer between client and server: http://blogs.telerik.com/VladimirEnchev/Posts/08-05-23/SQL_Server_sorting_paging_and_filtering_with_RadGrid_client-side_data-binding_to_WebService.aspx?ReturnURL=%2fVladimirEnchev%2fPosts.aspx
ViewState size: Some of the grid operations can work with completely turned off ViewState. Example: http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/Programming/ViewState/DefaultCS.aspx
In client-side data-binding scenarios you do not need the ViewState also. Example: http://www.telerik.com/DEMOS/ASPNET/Prometheus-futures/Grid/Examples/Client/DataBinding/DefaultCS.aspx
HTML output size: RadGrid output is the smallest on the market however may depend on selected grid features, number of items per page and templates. Example: http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/GeneralFeatures/Migration/DefaultCS.aspx
JavaScript file size: The entire grid script size is 174 Kb (combined and compressed using dojo)
