Application Initialization - no warnings, no effects

Hi all, I have SharePoint Application (on IIS 7.5) which should be preloaded. It is under address: http://mycomp:1003/sites/XYZ/Pages/page.aspx I've put this into applicationHost.config:

<add name="SharePoint - 1003" autoStart="true" managedPipelineMode="Integrated" startMode="alwaysRunning">

....

<site name="XYZ - 1003" id="174843041" serverAutoStart="true"> <application path="/" applicationPool="SharePoint - 1003" preloadEnabled="true">

and in web.config file of this app:

<add initializationPage="/sites/forsn3/Pages/SolutionDescription0.aspx" /> </applicationInitialization>

But when I restart IIS (iisrestart) there is only one w3wp process which uses CPU for about 4-5 seconds and that it's all. My page.aspx loads exectly as slow as earlier... In event log under Application node there are no errors or warnings. What is wrong???
