Profiling of real-world web applications
Hugo Aguiar, João Costa Seco, Lúcio Ferrão · 2010
Non-functional requirements of enterprise web applications, like performance, are usually assessed and analyzed in simulated environments before being released into production. However, it is not easy to simulate a real-world environment and the effective use of the system, leading to poor and expensive performance data collection. Moreover, in agile methodologies, where development is focused in the fast time to market and getting early feedback from end-users, upfront estimation and forward thinking about scalability is not in the top priorities. This constrains even more performance analysis and tests, as developers are only aware of performance issues when critical feedback from production systems is given back to development. This commonly leads to enterprise web applications with scalability problems, and low responsiveness.
