Instead, the resource data is contained within the URL string itself as a baseencoded string. This saves the browser from having to make additional HTTP requests for the external resources, and can thus increase page loading speed. Minimizing the number of browser requests is an important part of optimizing web page loading times. So Data URLs can thus have beneficial effects on performance. The transfer speed may thus be held back by the overhead of TCP communication.
