Optimize Parallel Downloads to Minimize Object Overhead. Summary: With the average web page growing past 50 external objects, object overhead now dominates most web page delays. Increasing parallel downloads by using multiple hostnames can realize up to a 40% improvement in web page latency. With the average web page made up of more than 50 objects (Krishnamurthy and Wills 2006), object overhead now dominates the latency of most web pages (Yuan 2005).
Following the recommendation of the HTTP 1.1 specification, browsers typically default to two simultaneous threads per hostname. As the number of HTTP requests required by a web page increase from 3 to 23, the actual download time of objects as a percentage of total page download time drops from 50% to only 14% (see Figure 1).

Images are considered replaceable elements on the page, because it is possible for the browser to allocate space and layout for the element and continue rendering the rest of the layout and page. In order for the browser to allocate the slot, it needs to know the dimension of the element which is the image ahead of time and definitely before the image is downloaded. Once you have optimized the image, specify the dimensions wherever possible… Google Publishes Guidelines For Optimizing Mobile Site Pages Mobile Web Site Design and Development forum at WebmasterWorld.
