My Adsense earnings on a quality site has gone down a lot since start of November. The site use to make me around $100 a day regularly. The ecpm as well as CTR is down around half. The traffic being roughly the same as before.
Google did send me a message in my Adsense account that some popular pages were loading slowly and that it could lead to big loss in revenue. However, when I use speed tools it appears the pages take around 3 seconds, and even when I visit the pages myself it doesn't appear slower really.
