Your company is rolling out its new web application. This web application is well designed and attractive. It has been well tested by the quality assurance group. You’ve spent a lot of money marketing your website. The site now goes live. In the near future you realize your brand-new web application is unable to scale for your typical production load plus the response times and gratification reach completely unacceptable levels. Internet logs indicate that most of your prospects simply leave the newest website before purchasing anything since its response times are extremely poor. You set about to panic, then one of one’s friends says to you how the reason your application does not perform adequately is basically that you will not have ample hardware. Hearing this, you may add more server hardware. While this includes a small impact on your website response time, it is still woefully inadequate. You soon know that problem isn’t going to really lie using the hardware but instead with the web application itself. Apparently your online application was not well optimized with the typical peak loads. It might be increasingly evident that many of one’s marketing dollars were wasted.
It can be use less to get load test that does not reflect the particular usage and will also be dangerously misleading. For ex: this will give you the information that is certainly the overestimate or even an underestimate with the website capacity and scalability ultimately causing disastrous consequences.
Metrics are utilized systematically to make, develop and test load scenarios that simulate, as accurately as you can, real load situations. To measure how closely a load test matches real-world usage, we developed the thought of Site Usage Signature (WUS). The WUS is usually a group of metrics and measurements that, taken collectively, yield a very comprehensive picture of Web site activity.
In the event the WUS from the load test does not match closely the WUS from actual usage, it is best to seriously question the validity and applicability of the conclusion used by the tests. Conversely, when the two WUS’s are matched, in that case your level of confidence that any results connect with down to earth situations increases considerably. Since every Web page is different and requires to track site-specific metrics, there is absolutely no standard format or standard group of metrics for that WUS.
An additional thing is to include enough measurements so it will be tough for two signatures to suit closely unless the 2 main leads are closely matched. Having realistic load tests greatly simplifies the duty of producing and testing load scenarios.
Latency tolerance is undoubtedly an indicator of methods long an end user will wait for a page to load before becoming dissatisfied and, possibly, abandon the Web site. A lot scenario can be achieved a lot more realistic by simulating the behaviour of tolerant and intolerant users.
