Using p_trace=YES

Question

One of my pages was very slow to render and I suspected a query region on the page. So, after the page loaded, I went to the Location bar in the browser, added &p_trace=YES to the URL and hit Enter.
I ran tkprof on the resulting trace file and it showed a total time for all statements as only 3 seconds. But the page took nearly 15 seconds to load.
Why would this be? Where is the rest of the time being spent?
Thanks
