Incredible! All references to Adsense performance problems are gone from "Webmaster Tools - Site Performance"
BUT, all the performance problems still exist!

It appears Adsense has influenced webmaster tools not to show anything related to Adsense performance issues!

It works out to 69% of the page load time is due to Adsense! 69% of the bytes downloaded are due to Adsense! This page that loads in 6.97 seconds on a DSL connection would load in 2.14 seconds without Adsense! So for my 62K of original CONTENT; Adsense required 139.5K of downloaded scripts and data to show ....

Adsense inefficiencies summary:
Javascripts:
show_ads.js --------(Original Script now very large!)
sma6.js ------------(Scroll bars for ads)
test_domain.js -----(How to fetch showads.js. Appears to be unneeded)
expansion_embed.js -(Haven't looked into this one!)

Unnecessary GETS:
Up to 5 unnecessary references to the showads javascript. (This is a complete waste of time!)

Domains:
googleads.g.doubleclick.net
pagead2.googlesyndication.com
csi.gstatic.com/csi
Used to be one domain.

Finally Google Analytics was also reported as a performance issue. Perhaps it's fixed? (I deleted it from all my sites)
