Google’s current goal is to get Gmail to load in under a second. “Speed is a feature,” he said.
Early tests have proved promising. For instance, Gmail looks for those browsers that can work with version 3 of the Cascading Style Sheets (CSS), a standard closely related to HTML5. If the browser supports CSS3, Gmail will render the pages using these specifications, rather than its traditional approach of using the Document Object Model (DOM). The company has found that using CSS3 can speed the rendering time by 12 percent.
