There are three main reasons why front-end performance is the place to start. 1) There is more potential for improvement by focusing on the front-end. Cutting it in half reduces response times by 40% or more, whereas cutting back-end performance in half results in less than a 10% reduction. 2) Front-end improvements typically require less time and resources than back-end projects (redesigning application architecture and code, finding and optimizing critical code paths, adding or modifying hardware, distributing databases, etc.). 3) Front-end performance tuning has been proven to work. Over fifty teams at Yahoo! have reduced their end-user response times by following our performance best practices, often by 25% or more.

Reduce Page Loading Time With PHP Each one of these uses up time on your page loading, so to reduce page load all you have to do is reduce the amount of calls being made. But what if you want to organise you JavaScript files, jquery file, general file, application file and page file. There could be upto 4 requests for some javascript for the page. It is possible in PHP to combine these JavaScript files together and trick the browser into thinking they are just one JavaScript file, therefore reducing the amount of calls being made to the server. This is done by reading the JavaScript with PHP then changing the header to JavaScript like the
