The objective of this paper is to investigate and optimize the performance of web sites and take steps to improve the end-user experience. Taking site's loading speed into consideration is still something we should really look for. Extensive literature is there on website popularity, content-based, collaborative or knowledge-based filtering etc but there has been a little work regarding performance optimization of individual website. Web site performance optimization checks for various referenced resources such as JavaScript, CSS, HTML status code, HTTP request, response time, DNS lookups etc. A key indicator of the performance of any web site is its referenced resources. Web applications need to be monitored in an objective manner to ensure optimal performance translating web performance to dollars and cents. As users are in hurry and don't feel happy if their web site is responding slowly in several seconds. Hence the site is contingent to lose a lot of visitors. This paper purely illustrates the parameters by which web ecosystem can be improved. One website was created to measure parameters and impact of execution on the responsiveness of the website. The performance can be measured by sampling site on the basis of milliseconds a site takes to load and can also view time-based response that gives a fair idea of the performance of websites over a interval of time. If a constant degradation of performance is noticed, then necessary actions can be taken to improve it. By spiriting images, minifying JavaScript, CSS, zipped files and html tags the response and loading time of website has reduced to a great extinct. The performance can be evaluated by using tools which give details of resources and components on that web site. They give the option to understand how the site is loading with different global perspective, visitors, page size and Internet connection speeds.
