Page_init and Page_prerender methods - performance issues

We were running a simple aspx page on IIS7.5 and we observed that it is taking long time to exit Page_Init method and call Page_PreRender method. There is nothing getting executed between these methods. See trace for the page calls.

[INFO   ] 2011-07-15 18:30:24,783 [6] Customer.Ektron.Web END - Page_Init() 
[INFO   ] 2011-07-15 18:30:27,486 [6] Customer.Ektron.Web START - Page_Pr开发者_如何学CeRender 

Wondering if anyone has experienced this before.. This is simply killing our application performance..

That looks like the output of log4net, and not the default /trace.axd handler.

Between Init and PreRender comes the Load event which, I believe, is the default event for doing any work [in tutorials]. There are also other events, like InitComplete, PreLoad, and LoadComplete which executes, and there's state (viewstate and controlstate) loading if it is a postback, including raising any postback events.
