Ilya Grigorik, Google's "Developer Advocate, Make the Web Fast and Google Chrome" shared on Google+ that Google Analytics has a new report named "Page Speed Suggestions".
This report shows you your page speed load times for all your pages, sorted by default by most pageviews and then you can click on them to get a report on how to improve things.
The report itself is run in real time according to Ilya. Ilya said, "it's updated everytime you load the report... which also means that if the pages themselves are slow, you might have to wait longer for the report to come up."
Here is a sample of the report:
You can access it under behavior > site speed > speed suggestions. There is a more detailed blog post on this at Google Analytics Blog.
