Abstract: An important functional requirement for the EDEN-IW prototype is linked to overall processing speed. In other words, it is important that the user gets the desired information in a timely acceptable manner. A system response time in the order of a few minutes is in most cases considered acceptable by the user, but if this time span from request to reply exceeds, for example, 5 minutes, the user will in most cases abandon the use of the system. To explore this issue, a series of computer investigations were made. These have illuminated where in the system the major time was spent during the different queries. Being aware of the most time-consuming elements in the process could significantly facilitate a future tuning of the prototype to comply with the expected increased demand of the amount of data to be presented to the user by the system.
