I've noticed Adsense querying yet another domain! This query is embedded in the code in the Adsense IFrame.
This requires yet another DNS fetch to another domain, very inefficient.
Just a note I use text ads exclusively. I've never had much luck with image ads, they are very slow, delay rendering, and really don't pay well. Could just be my site(s) type of extensive content. Text ads and link units work well.
And I think Adsense may querying yet another domain.
This is getting to be way too much overhead. All of this could be much more streamlined speeding up all sites using Adsense.
