    I have recently converted my application to Telerik UI. It was fine before conversion into Telerik but now, after installation on client side, they're complaining for very slow performance. Forms are taking time to load.


    Can you please tell me why its happening? Any bug you have noticed in your current version?

    Hello Shahid,

    Thank you for writing.  

    The following Knowledge Base article demonstrates some performance tips when using the Telerik UI for WinForms suite:

    However, the provided information is not enough for me to replicate the performance issue that you are facing. Could you please specify the exact steps how to reproduce the problem or get back to me with a sample project so I can investigate the precise case? Feel free to attach the project in the support ticket that you have opened on the same topic. Thank you.

    I am looking forward to your reply.

    Hello, Ranees,  

    I would like to let you know that our controls provide rich UI capabilities and theming mechanism which inevitably increases the memory usage. Furthermore, our components are built from the Telerik Presentation Framework which is built on top of the .NET Framework which once again, inevitably increases memory usage compared to other controls, such as the standard controls which simply wrap native objects.  Unless a certain control has a memory leak it is eventually being disposed. Calling GC.Collect will not dispose the objects immediately, they will simply be marked for disposal and the next time the Garbage Collector passes by it will decide whether they are suitable for actual disposal. This is due to the non-deterministic behavior of the Garbage Collector. Our objects are mostly from Generation 3, which means that they will be disposed at a later state (more about garbage collection).

    If you encounter any memory exceptions, I would kindly ask you to submit a support ticket from your account where you can provide a sample project demonstrating the undesired behavior  that you are facing. Thus, the Telerik support would gladly assist you. 

    Note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread. Thank you for your understanding.

    I hope this information helps.
