"1. According to Google Analytics my site speed didn't improve!
2. According to my Adsense account there was $*** invalid traffic. More than 50% of my Adsense income vanished because Google thinks it was invalid traffic. "

The only feature that we have that might impact AdSense is Rocket Loader. Did you have it turned on?

If you had an issue, however, it is much easier for us to investigate with an actual support ticket with the domain.
