I have ~200 object types and 10 modules , in a P4 , 3GHz  , 2GB RAM   laptop it takes 45 seconds for login screen to appear.

has anyone faced this issue?.

when I started with the project it was acceptable (<5seconds) , but when more rules and customization are added this got slow.

the time taken is in ApplicationModulesManager::LoadModel (50% for UpdateModel and 50% for LoadTypesInfo ).

Peter,

Does this occur in DebugMode (e.g. do you run from Visual Studio), probably under the Visual Studio Hosting Process, or are you talking about a Release Version?

As far as I know, by default a Xaf application outputs a lot of trace information. Changing a value in your app.config might help. Try setting the value for eXpressApFramework to 0..

<system.diagnostics>
   <switches>
      <!-- Use the one of predefined values: 0-Off, 1-Errors, 2-Warnings, 3-Info, 4-Verbose. The default value is 3. -->
<add name="eXpressAppFramework" value="4" />
      <!--
<add name="XPO" value="3" />
-->
   </switches>
  </system.diagnostics>   

Will you please let us all know the results? Currently, I'm not up to 200 object types yet, although I do have about 15 modules already (I favor separation of concerns)...

Marco

Talking about Release version with Trace = 0

What about your system configuration and OS? (just curious, i'm afraid I don't have a solution for you)...

 It is not issue with one PC , all PCs have this problem.
