I tried to improve the performance of my website by enabling the combine script option in RadScriptManager.
<telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableScriptCombine="true" >
However, i found that the page loads slower than disabling this feature in the initial load (no cache in the browser).
With the help of fiddler, i can see that the actual transfer time is faster but seem the browser take longer time to process the script.
And the size of the combined script is much larger than seperated script resources.
Here is the figure:
combined : 272,245
Individual : 17,324 + 18,714 + 5,147 + 9,743 + 10,319 + 7,074 + 17,994 + 4,841 + 10,097 + 1,705 + 9,224 + 2,588 = 114,770
