Manual talk:Profileinfo.php

Hi, I don't know if this is the right place to put my query or not, but I don't know any other so I am asking it here. We have an internal wiki in our organization. I want to know if mediawiki's built-in profiling can be enabled on extensions also. Also, will profiling be helpful for logging purposes (like log4php) If yes, it will save us from a lot of overhead.
