<blockquote>Research indicates that SVG images served as an image sprite display faster than SVG images as data URIs. But how much faster? And is it worth your time? If it is, how do we actually produce the SVG sprites? This post looks at different data on the sprite versus data URI question and how to configure a couple of automated Grunt tasks to produce SVG image sprites and fall back PNG sprites (rather than data URIs) to provide resolution independent interface icons if you so chose.</blockquote>
