Behavior Section has information about average speed of page loading, server response redirects and other parameters that affect the speed of your site. You will also receive a detailed report on the speed of a site in certain browsers and by different countries.
Google also recommends to check your web site according to Google Webmaster Technical Guidelines. In addition to its own tools, experts suggest using the Google browser extension Mozilla Firefox YSlow on the site and check WebPageTest.
