Google publishes stats report about web

Google has recently published a report about the Web, which includes a lot of interesting stats. The results were obtained from a sample of 4.2 billion web pages indexed by Google.

Recently, Google has published a report about the web that has more stats that are interesting. Really, 4.2 web pages are indexed by Google to obtain the results. Usually, the average web page takes up 320 KB on the wire. Moreover, only two-thirds of the compressible material on a page is actually compressed. At the same time, in 80% of pages, 10 or more resources are loaded from a single host.

29.39 is the average number of images per page and the size of all the images from a page is 205.99 KB. A web page has an average of 7.09 external scripts and 3.22 external stylesheets. 57.98 KB is the average size of the scripts and 18.72 KB is the average number of the stylesheets.

Moreover, Google has found that only 17 million pages from sample use SSL (about 0.4%).

If you are a developer and want to improve the performance of your websites, you can have a lot of tutorials from Google. However, Google recommends to use Gzip compression, use HTTP caching, optimize JavaScript code and properly combine scripts and stylesheets.

Urs Hölzle, Google's Senior Vice President of Operation, said that the average web page takes 4.9 seconds to load and it makes 44 calls to different resources. "Speed matters. The average web page isn't just big, it's complicated. Web pages aren't just HTML. A web page is a big ensemble of things, some of which must load serially," said Urs Hölzle.

New Micro battery, power packed for high performance

For a size of a few millimetres, the new micro-batteries are powerful enough to jump start a car battery and then quickly charge the cell phone. Researchers from the University of Illinois have developed the micro batteries which can be used to drive compact electronic devices and new applications for radio communications. The micro batteries are so good that they can even out power the super capacitors. The results were published in ‘Nature Communications’ in the April 16 issue. The micro batteries have energy and power and with the researchers tweaking the structure of the micro batteries a little bit, its use can be for wide range applications. The high performance of the micro battery is based on its 3-dimensional micro-structure. Based on the design of fast charging cathode by Professor Paul Braun’s group, researchers developed the matching anode and integrated it with the fast charging cathode at a micro-scale and made a complete battery with high performance. These batteries cou
