There is little doubt that performance issues play an important role in web applications. Only few situations are as boring as sitting at a computer facing a web browser and waiting for a (usually dynamically generated) web page to appear. This paper discusses important aspects of empirical performance evaluation and tuning, which can be a rather complex task because of the standard structure of web-applications - usually there is more than one server involved. To evaluate the performance of the application empirically, the reply time of request and internal performance measurement techniques are used.In the context of a real life intranet information system, we elaborate both, on evaluation and tuning of web server as well as database server performance.As a result of the performance tuning steps presented in this paper we reduced the turn around reply time for typical pages of the tuned application from approximately 300 seconds to 80 seconds on average.
