WPF apps slow for some reason

WPF apps slow for some reason

• DamianH

  Hi,
  
  I finally managed to get the newest WPF CTP (November) running on my computer, so I tried again, but I'm still experiencing the same slowness.
  
  Any sort of interaction with any control seems to make it slow, especially buttons and such. And it seems to be in both XamlPad as well as in a simple app compiled with the WPF template in VS2005.
  
  I'm on the same machine as before, except with the most recent video card driver.
  
  Clicking on the buttons 2-3 times consumes 100% CPU time with the following code from the Quick Start tutorial on msdn here:
  
  

  <DockPanel xmlns="http://schemas.microsoft.com/winfx/avalon/2005"> <TextBlock Background="LightBlue" DockPanel.Dock="Top">Some Text</TextBlock> <TextBlock DockPanel.Dock="Bottom" Background="LightYellow">Some text at the bottom of the page.</TextBlock> <TextBlock DockPanel.Dock="Left" Background="Lavender">Some More Text</TextBlock> <DockPanel Background="Bisque"> <StackPanel DockPanel.Dock="Top"> <Button HorizontalAlignment="Left" Height="30px" Width="100px" Margin="10,10,10,10">Button1</Button> <Button HorizontalAlignment="Left" Height="30px" Width="100px" Margin="10,10,10,10">Button2</Button> </StackPanel> <TextBlock Background="LightGreen">Some Text Below the Buttons</TextBlock> </DockPanel> </DockPanel>

  Hey, Teymur, you should tell us your hardware specs first

  I've got a corrected version of the link that should work:  http://www.designerslove.net/docs/Optimizing%20Performance%20in%20the%20Windows%20Presentation%20Foundation.doc

  Hello Rei -
  
  Check out our performance whitepaper; it may have useful information for optimizing your application's performance.
  
  Thanks

  It's at 32 bit.
  
  It seems to be worst when there's a lot of interaction -- text boxes, buttons etc. Images and animations seem to be fine.

  Rei, does the slowness ONLY occur when running sample in XamlPad   If so, then I'm thinking some version incompatibility, or something went wrong during one of the CTP installs.

  Just in case it is an install issue, I've cut and pasted the instructions I wrote to myself, for developing under Visual Studio.  I'm not using XamlPad, so I don't know if you need all 4 pieces below for what you are doing.

  ----------------------------
  Here are the four pieces that need to be compatible (and it matters what
  order they are installed) - do you have all 3 of the September CTP pieces :

  #1. WinFX Runtime Components - September CTP - 9/14/2005
  http://www.microsoft.com/downloads/details.aspx familyid=FFD636F0-86E9-41E8-9E1C-100A4CC4888F&displaylang=en

  #2. WinFX SDK - September CTP - 9/14/2005
  http://www.microsoft.com/downloads/details.aspx FamilyId=C20CC6C8-1F4E-4A5C-BC79-C2FE9ABE69AA&displaylang=en

  #3. One of the Beta 2 versions of Vis Studio 2005, currently online at
  MSDN Subscriber Downloads > Developer Tools > Visual Studio 2005 >
  Visual Studio 2005 Beta 2 > English >
  . Visual Studio 2005 [..Professional, Standard, or Team Suite..] Beta 2
  -or-
  Visual Studio 2005 Express Products Beta 2 > English >
  . Visual [C#, etc.] 2005 Express Beta 2

  *** NOTE: NOT the "Release Candidate" that is currently available elsewhere
  for download ***

  #4. Visual Studio Extensions for WinFX - September CTP
  http://www.microsoft.com/downloads/details.aspx FamilyId=EDE1A645-2A53-42E1-8482-3BF1FADADE06&displaylang=en

  *** NOTE: the FIRST thing to try, is REINSTALLING piece #4 ***

  Thank you for immediate answer. I simple selected file/new/project and winfx application. and placed button on it. The clicked F5. That is what I have done and result is slow. For your solution: I am beginnner in WINFX and VS 2005 EinFX templates. Where do I i have to check this option Thanks in advance. Teymur

  It occurs with practically everything. And yes, I've tried uninstalling and reinstalling everything in that order several times.
  
  I probably messed up some installs along the way; every time I reinstall things seem to get worse and worse. Now .xaml icons don't show up properly, and WinFX Beta 1 doesn't work either.
  
  So I've given up for now. I'll give it another shot if I ever get my hands on a copy of Vista :)

  What bit rate is your monitor set at Currently we only do hardware acceleration if you are set at 32 bit color.

  Hi, thanks for responding.
  
  I get a 403 when I click on the link on the page for some reason... I'll try again tomorrow.
  
  Thanks!
  

• kedens

  Make sure you don't have any transparent windows running, this will bring down the performance in all wpf-apps.

  I also get that Forbidden - 403 Error when attempting to follow the link to:

  Dear All.

  I installed 2006 June CTP. I am in XP Service Pack2.

  AS Rei Miyasaka told, it is very slow when running application with simply only one button.

  Why it is slow Have you found solution for it I work with VS 2005 WinFX template - Windows application.

  Thanks in advance

  Teymur
