To evaluate the performance of distributed web servers, we have built a cluster-based web server with eleven nodes in our laboratory to conduct measurements of fine granular performance data like individual per-packet delays. We implemented a precise GPS-based time synchronization solution and a software monitoring solution for high-volume measurement of one-way delays in the range of microseconds. The obtained data is used in the input modeling phase to parameterize and calibrate our UML-based simulation models for the web cluster. Additionally, we use the measured performance figures to validate and verify the output of our simulations. Our models help us to scale cluster-based web server systems for a given application to deliver a demanded quality of service level. © 2005 EUROSIS-ETI.
