A fileserver receives requests at an average inter-arrival time of 0.0333 sec. Measurement data indicate that the average service time of a request is 15 msec. 

1. What is the average response time, utilization and throughput at the file server? 

 2. If the arrival rate doubles, what impact does it have on the above mentioned performance metrics.

3. If the system is now closed with 5 users with think time of 200 msec, what happens to the performance metrics above
