Performance modeling is an important topic in

capacity planning and overload control for web servers. We

present a queueing model of an Apache web server that uses

bursty arrival traffic. The arrivals of HTTP requests is

assumed to be a Markov Modulated Poisson Process and

the service discipline of the server is processor sharing. The

total number of requests that can be processed at one time is

limited to K. We obtain web server performance metrics

such as average response time, throughput and blocking

probability by simulations. Compared to other models, our

model is conceptually simple. The model has been validated

through measurements and simulations in our lab. The performance

metrics predicted by the model fit well to the

experimental outcome.
