we only run html code with adsense
Adsense has much more of an impact on page load time than analytics.
We moved to a much bigger & better dedicated server & it still reports we are slower
Download the Firebug addon for Firefox and use the Net tab to see which components of your page are slowing you down. It makes for interesting reading.
I added Adsense to one of my sites and went from 1.5s response (faster than 80% of sites) to 2.5s (faster than 55% of sites).
