I am wondering what other people see when they look at tools.pingdom.com as far as adsense related requests.

I have one site with 3 adsense ads and see about 100 requests in tools.pingdom. I have another site with pretty much the same format only 2 adsense ads. It has over 300 requests usually but sometimes that number goes up to 600. It all looks ad related. (advertising.com, lkqd which does video ads even through I don't run video ads)

Does anyone else see this? I wonder if I have some old code lurking around causing issues.
