The ability to track performance of an application or application suite over time is extremely valuable to our business partners and for our application development team with near real time results. Additionally the ability to track both real and synthetic user performance and compare real to synthetic user performance as a baseline is important to us on several fronts; real users make human decisions and we can see how their performance compares to "perfect" synthetic users running scripts to do similar tasks. And because our synthetic users run consistently 24/7 we also can compare peak traffic performance to off peak performance.
