Optimize Front-End Web Performance to Ensure Highly Satisfying Experiences
Deliver fast, feature-rich applications that lead to customer satisfaction, brand loyalty and sales

While AJAX can make websites and web applications seem faster and more engaging, it also results in more application logic sitting in the web browser than ever before. This produces a greater impact for browsers overall on end-user experiences, which makes it critical to measure and optimize the performance of dynamic web applications at the browser level.
In this article, we'll show how consumers increasingly find website and web application performance issues unacceptable. We'll discuss the evolution of AJAX, and why "server-side" solutions alone are no longer sufficient to manage performance for complex AJAX web applications. Finally, we'll highlight industry developments that are making it possible for companies to ensure high-performing AJAX web applications and, consequently, more satisfying and profitable end-user interactions.
Web Application Performance Equals Money
This is known as the "Google Effect," where customers expect all the web applications they interact with to be as fast and engaging as Google. For the average user, 0.1 seconds is an instantaneous, acceptable response, similar to what they experience with a Google search. Not surprisingly, companies are investing heavily to make sure they deliver highly satisfying, feature-rich websites and applications. One approach they are taking is adopting web development techniques like AJAX for the front-end of their applications.
The Evolution of AJAX
With AJAX, feature-rich web applications can now be dynamically served up to end users much more quickly and efficiently than in the past. In contrast, in the 1990s, most web sites were based on complete HTML pages. Each user action required that the page be reloaded from the server, or a new page loaded. This process was highly inefficient, increasing end-user wait times due to excessive server round-trips.
Solving the AJAX Performance Management Challenge
To remedy this problem, new solutions are available that enable organizations to test and diagnose AJAX web application performance issues. Leveraging a new generation of application performance management (APM) centered on the end-user experience, these solutions provide organizations with a bird's eye view into how dynamic AJAX web applications are performing for real end users across a variety of browser types. This empowers organizations to pinpoint and address browser-specific problems that could be inhibiting a world-class, end-user experience, including long-running Java script code, excessive DOM calls, slow AJAX invocations or problems with rendering. In essence, organizations can analyze forensics on all activities within dynamic page components as they are presented to end users.
