A slick-looking Web site is ultimately of limited effectiveness if all of the its bells and whistles are an impediment to system performance. Hence, the monitoring of system performance at the end-user/UI level is extremely important to ensuring a consistently excellent user experience. By using the proper website performance tools in a targeted manner, both business managers and developers can effectively monitor the impact of third-party performance both on the individual component level and in the aggregate.
The more complex your Web site is, the more likely it is that its performance – and possibly your profit margin - is in the hands of third parties and their components running on your site. Ideally, we want to improve the performance of these third-party components (aka “widgets”), so that a page loads just as fast with these widgets as without them.
If you are the owner of the Web site, there are at least two ways to improve overall site performance. One is to optimize the Web site itself for each widget so that those widgets running on the page will be more efficient, a method that is not cost-efficient. The other, more cost-effective option is to use continuous and focused website performance monitoring. Breaking down performance by time and by component category allows you to pinpoint the components that adversely impact Web site performance.
