Minify ScriptResources.axd files rendered with RadControls on aspx page.

[Riz]

Hello Telerik Team,
 
We have web application built in asp.net 4.5  with Telerik (version 2014.2.724.45) controls. We are facing  performance issue with our application. 

We inspected our page just to check what all size of data does it renders on a browser. 

It renders about 600 KB of data on the page out of which 
 i) About 300kB is JavaScript  
 ii)About 80KB is css 
and rest being the HTML that are rendered and other data that is rendered on the page.

We Bundled all our CSS and JavaScript file on the page. While tracing the content we also came through Scriptresources.axd and WebResources.axd out which WebResources are already minified.

But Script Resources file are not compressed or minified. Total size of this files is about 160KB. We tried different way of compressing or minifying them but so far didn't get any way to do this.

We would like to request you to provide a possible way where we can minify this SecriptResources.axd file.

Thanks,
Riz

Hi Riz,

Scriptresources.axd is generated the the asp:ScriptManager and IIS should be able to minify this handler's responses when its dynamic content compression is enabled.

If you want to further optimize this, I advise you go through the following help article: http://docs.telerik.com/devtools/aspnet-ajax/general-information/performance/optimizing-performance. Key points:

• RadScriptManager can combine all scripts requests in a single request
• RadScriptManager can let you use CDN for our controls (and you can also use a CDN for the MS AJAX framework) which improves caching and takes load off your server
• You may want to look into upgrading to be able to use the combined script resource for our controls
• RadStyleSheetManager can combine stylesheet requests and provides skins CDN for our controls, including a combined request for the base stylesheets
