ADVERTISEMENT 15s 1.5s 0.5s Ajax framework solutions based on LoadRunner Click and Script technology, which reduces the scripting process to a few mouse clicks • Performance validation for Flex • Performance validation for web services • The planned addition of client-side breakdown • 0.5s 0.3s 0.7s 1.5s In this example, load times for different page components range from 0.3 seconds to 15 seconds. To validate performance under these circumstances, you need to be able to test the end-user experience under different loads. For example, what happens when one user completes a drag-and-drop action? How much time does it take for the page to reflect the action? And then what happens when a thousand users complete the same action at the same time? To understand how your applications will work in a Web 2.0 production environment, you need to be able to simulate not just the actions of one user, but the actions of many users, perhaps even thousands of users. These are among the actions that cannot easily be duplicated without the proper automation tools. Break down the page to speciﬁc components and isolate performance issues. With Web 2.0 applications, it is no longer enough to test the amount of time that it takes for an entire page to load. Instead, you need to test the amount of time that it takes for different components of a page to be updated. To do this, you need to break down a page into specific components and then isolate the performance for each. How fast does the skeleton of the page load? How much time does it take for stock quotes to appear on a user’s home page? Or how much time does it take for an updated list of employee names and numbers to appear in an ERP application? HP performance testing solutions allow you to answer questions like these by emulating the actions of hundreds or even thousands of users and then capturing the response times for key processes and transactions—so you can optimize your applications for better performance. Test the performance for complex web operations. With Web 2.0 applications, there are fewer web-page refreshes but much more interaction with back-end servers. While some changes to pages might not require interaction with a server, many user actions trigger interactions with back-end servers. With HP Software, you’re ready for Web 2.0. HP Software offers the key capabilities needed for performance validation of Web 2.0 applications. Product offerings for Web 2.0 performance validation include HP LoadRunner software and HP Performance Center software.
