Hi, my name is Steven from a software company. We are developing a project to the government using Telerik Window Component.
We are facing an slow performance issues in the client PC with the RadForm. 

1) When I tried double click the .exe file to load the first page (We use RadForm as first page) of the window application. The Form only contained 2 RadTextbox and 2 RadButton, but it took 10 seconds to be appeared after double clicked on the .exe. The form doesn't have any connection to the database.

2) When I tried to click to open another form (RadForm), it took about 11 seconds to complete loading the form (This form contained more telerik controls).
 
Does it caused the slowness with more than 20 Rad Controls in a page?

Appreaciate if anyone could help me on this issues.

Thanks.

Hi Candide,

Thank you for writing.

When loading an application for the first time all controls should be initialized and themes should be loaded. Unlike the default WinForms controls our suite offers animations and themes and loading them takes its time. This time increases when using a lot of controls like in your application.
The following KB articles summarize all possible way that we know to optimize your application.
Make your Telerik WinForms-enabled applications start instantly.
Performance considerations.

However, could you please provide more information about your case? I would kindly ask you to send a sample project which demonstrates your scenario. This will allow us to investigate your specific case and think about the possible ways to optimize it. Please note that you have to open a new support ticket in order to be able to attach your files.

All the best,
Peter

Hi,
I have a legacy app that opens some forms in a Telerik app (We're trying to migrate the whole application).
So, I'm calling the C# .exe with args to open a Form, it takes a while to load Telerik resources.
I'm trying to let this C# .exe open in background to call it and open the form in a new thread.
How can I send the arguments to this open Application?

I noticed when Telerik is installed on developers machine, the radForms opens instantly.

Is there a way to load all Telerik resources and keep them in memory?

Hello Jose,

Thank you for writing.

Let me get straight to your questions:
1. The Process.Start method automatically runs on a separate thread and it accepts arguments where you can pass your data. You can find additional information here: Process.Start Method
2. On a developer machine the Ngen.exe (Native Image Generator) cache allows a faster loading time. I think that you can find the following blog post useful: NGen: Creating Setup Projects
3. Yes, there is a way to keep all resources in memory and start the Telerik app instantly: Make your Telerik WinForms-enabled applications start instantly

I hope this information is useful. Should you have further questions please do not hesitate to write back.

Hi Hristo,

Thank you for the tips.

But, my application can not stay load.

Can I use NGen.exe to work in client machines? The 2º tip didn't work for me or I don't know how to use it!

Hi Jose,

Thank you for writing back.

Yes, you can use the Ngen.exe (Native Image Generator) on your client machines because it is part of the .NET Framework. When the app is first started its load time should be improved and the images will be cached by the .NET Framework. The Ngen basically does pre-compilation and stores the produced code in "native images" which are referred as the "Ngen cache". These articles provide additional information: Deployment and Ngen.exe, Performance and FeaturesNGen in Visual Studio

The following blog post discusses the performance of the Telerik RadControls and answers some frequently asked questions: Performance considerations

I hope this helps. Should you have further questions please do not hesitate to write back.
