Here are a complete discussion to optimize the performance of website
More and more, you hear about web performance as a criteria for positioning on search engines. This factor combines several indicators that allow Google robots to judge whether your site is fast and to combine it with other factors to determine the positions of your pages.

How to set up the browser cache system?
