Speed problems

[Michael]

After last updates we start to have problems with speed on our apps, loading time is incredible slow, not only in grids but too in silverlight scheduler.

I want to know if some of the changes done on these versions affect to these elements. Our problems are focus on rendering, because we measure sql times and webservices times and are ok. We test this in several clients an seems not related to hardware as we have found these problems on cloud web (Azure) or in IIS servers (we test and increase RAM, CPU, etc).

Hi Michael,

We are not aware of any performance problem with the latest R1 2018 release. The list of important and breaking changes is available here and the release notes here.

Can you please specify from which to which versions of the Telerik ASP.NET AJAX suite you have updated your Web Forms project?

For ASP.NET AJAX you can find optimization techniques and advices in the following resources: 
- Performance issues and high CPU utilization on the server caused by RadStyleSheetManager or RadScriptManager.
- Optimizing Performance
- RadGrid Performance
- Optimizing RadScheduler Performance

If you are unable to solve the problem, please open a support ticket and provide a runnable project along with instructions of how to reproduce the speed problems.

Please open a separate ticket/forum for the Silverlight components and if possible provide a runnable project where the problem can be observed. 

Best regards,
Rumen
