Performance problems

[Oscar]

Hello, I am having slow response times in an ASPX app that uses RADcontrols. Pages take too long to load.
I aslo noticed (dont know if it is related) a large number of .axd files appearing when the app is run in VS2010 (see attached image).
My questions are:
1) is this normal behavior (large number of axd files) or is somehow related to slownessa and can be improved?
2) where to start looking to improve performance?
Thanks

Hi Oscar,

How to optimize the performance of our ASP.NET AJAX components as much as possible you can see from this article on our site. In addition, you can examine the content from the individual chapters/topics in the controls' documentation concerning performance tips and tricks.

Note that the embedded resources that come from the common ASP.NET AJAX ScriptResource.axd handler are not within the scope of our AJAX components and cannot be controlled by us.

Kind regards,

Hello Sebastian,

Found this thread already hence posting my queries here.( Users feedback that we got as well) -

We have an ASP.Net application heavily based on RADControls. What we observed is

1. If the page kept idle for some duration(15-20 min) and then tried to do any action related to RadControls (RadCalnder, RadDateTime, RadGrid click events etc) , Page takes longer time to refresh than usual...almost 45 sec on an avg. Whereas during continuous operations it gets loaded within 15 sec. 

2. Also, on every internal postback within UpdatePanel, the page takes longer time to refresh in order to load new state. 

Any suggestions that you can think of ? We tried capturing the Network traffic but with no avail as nly .aspx request and WebResourceHandler request seems to take long time.

Appreciate an experts opinion on this?

Thanks,

Chetan

Hi,

Steps for improving grid performance are provide in the topic licked below:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/performance/grid-performance-optimizations

Give them a try and see if they help to improve the page performance.

Regarding your second question you can use RadAjaxManager instead of UpdatePanel and try optimizing performance as described here:
