    Hi

    We're experiencing slow inital loads when using the RadScriptManager EnableScriptCombine feature if there is moderate load on the page. 

    Why is the combining so slow? How can I speed it up? And why are other websites on the same server experiencing this slowdown aswell?
    Page A under load, Page B with EnableScriptCombine enabled slows down.

    I found the thread about disabling it and/or using a CDN. CDN isn't an option and disabling the combining results in ~20 more requests. 

    Thanks

    Hello Studach Joerg,

    Can you provide more details about the slow down, e.g. how are you measuring it, what exactly is slow, the page load or the web resource load?

    The loading of the resource, it can take up to ~10s if there is some load on any page on the same server. Im using the Net Tab in Firebug to measure it.

    The Telerik.Web.UI.dll has the file version 2009.2.701.35
    Is this fixed in a newer version? Or better, is there a hotfix for this version?

    Hello Studach Joerg,

    We have made some optimizations through the recent years, however nothing specifically to address such an issue as we have not encountered it.

    Can you please update to the most recent version (even if trial) just to verify whether there is an improvement in the loading times? Additionally can you replace RadScriptManager with ScriptManager and test whether the overall loading time is faster or not? (Perhaps the cause of the issue does not depend on RSM's combining operations and on the overall processing capabilities of the server.)
