Front end optimization methods and their effect

With the evolution of the internet the loading speed of the web pages has become a vital factor for their success. A few hundred milliseconds difference in the response time are enough for visitors to choose one page instead of its competitors. This paper describes the increasing demand for faster loading webpages and the need of methods for optimization of the web code in order to increase their speed. It describes the process of loading webpages in browser and lists several methods for front-end performance optimization. The understanding of the loading process allows the correct identification of the parts that can be affected and improved. It also helps for understanding the effect of these methods and the cases when they can be applied. Although the total effect of the optimization depends on the specific webpage the appliance of these rules does not only reduce the page loading speed but it also affects the total bandwidth and load of the web server.
