According to a study WebSiteOptimization.com between 2003 and 2011, the average weight of a web page has increased from 93.7 KB to 679 KB more this year. During the same period of time, the number of objects per page has more than tripled from 25.7 to 85. In addition, long-term statistics show that since 1995 the weight of a web page has been multiplied by 48 and the number of items multiplied by 37.
Technological developments have meant to offset this inflation so important that logically should have slow access time to pages. Compression techniques XHTML files reduce the size by half and the widespread use of caching have to significantly increase performance.
WebSiteOptimization.com cites in its study, another study indicating that the 500 pages of the most popular home had their weight reduced by 81% with these techniques. But one of the best ways to improve the speed of page loading is to optimize the source code.
An example: when you visit a site for the first time in this connection you download 507 KB (depending on the average over the year 2010). During subsequent visits, the initial weight load decreases to 98.5 K. In fact, the more you access the same Web site and the number of requests behind the scenes (especially with caching) decreases: 65 16 queries. Of course, the high-speed Internet has also helped offset much weight gain web pages.
For the record, here is a striking example of what was done on the Internet in 1996. Maybe some of you still remember the page templates.
