Tera Gold Websites are built with multiple purposes in mind – rendering rich visual experience, ease of navigation, e-commerce functionalities, ease of ongoing maintenance to keep pages up to date, and various other factors. Fast page download times or end-user response times are surely a critical requirement for the user but perhaps only on the wish list of a casual website designer/developer – the unknown and varying network characteristics of the Internet sitting between the user and the websites is a big challenge. The fact that websites are increasingly accessed by browsers on mobile devices such as smart phones and tablets with limited processing power and constrained bandwidth makes fulfilling fast-response time requirement harder and harder.
WAN optimization techniques which are hugely successful in corporate environments cannot be directly imported because the classical data center-to-remote site topology does not apply to a single user visiting multiple websites.
Big RS Online Internet portals such as Google and Yahoo follow best practices and build performance requirements right at the planning stages. They use sophisticated tools that can help in making web apps faster and faster for their end-users. One such tool that is really handy is YSlow from Yahoo. YSlow is a free tool that can be installed as an add-on to a Firefox browser (enabled with Firebug). It is intended for use by the website developers to help manage response time requirements. When you visit any website with Firefox browser, YSlow measures the page download time and grades the website page in 23 or so categories along with some good recommendations.
