Slow performance - ASP.NET ASPNET_WP.EXE and CSC.EXE Run after clicking redirect link

Question

I click on a link from one page that redirects to another page (Response.Redirect (page.aspx)).

The browser takes about 30 seconds and displays the page. I am trying to track why the page has taken so long to load.

There are two other custom controls on the page.

I commented out lines of code for each and both controls, and the page still takes about 30 seconds to load.

I set breakpoints in the Page_Load event for each of the controls, as well as page.aspx, and it will also take about 30 seconds after clicking the link from Response.Redirect to the first breakpoint.

I downloaded the task manager and clicked the link. I notice that aspnet_wp.exe and csc.exe are executing during this 30 second time frame.

I am wondering if there are any kind of code code synanigans when I wait for the page to load.

This only happens the first time you click on a link. Subsequently, it is not so slow.

I searched googled, but there is not much useful information about this. Does anyone have any ideas?

Thank,

The first time a page loads, asp.net will compile a large number of pages, almost every one found in one directory, including modules and DLLs found in bin.
