Unfortunately Google search has declared they are now using this "page load" time, to a limited extent, to rank your pages in the search results. So if you use Adsense your pages will load more slowly. SO, your rankings will go down, SO your earnings will go down. Excessive corporate interdepartmental competition can destroy corporations (I've been there).
If Google is like almost any other corporate organization the various departments compete, versus cooperate. Adwords is obviously the BIG DOG because they are closest to the CASH FLOW. (The closer you are to the cash flow, the more cash flows into your pocket).
I imagine Adsense is in second place being a source of cash flow due to the content network (publishers, us).
Finally there's Google Search which actually makes no money! They are considered overhead! I believe Google Search is in charge of webmaster tools.
Publishers are simply caught up in this Google corporate conundrum! Good luck to us all!
