file w3wp.exe high cpu

Hello:

The file of w3wp.exe IWAM_Services, is giving enough war me, is
surely that some programmer (and I do not want to bother to anybody), has
had
brilliant idea to be giving cane to the .NET process, I know some
softs like iistracer that it can see the pages that are
executing and that esten generating a use of this too high service.

Do you know some soft, that can control pages webs that is loaded from
iis, that is not the previous one named by my, and who is simple and she
does not put
too much sweepings.

Or if there is some form from iis or from some type of process by which
can know that page is generating that great consumption of CPU?

Regards
