Consider a LAN (Large area network) that connects 100 personal computers and a server that maintains a common database for a query application. The average time for the server to respond to a query is 0.6 seconds. At peak times the average query rate over the LAN is 30 queries per minute. Assume that queries come in randomly. Imagine that the time for signals to travel between the computers and the server is negligible.
a) What is the average response time of the server, from the user perspective? ______ seconds
b) If a 1.5 second response time is considered the maximum acceptable, what percent growth in message load can occur before the maximum is reached?_______ %
Note: Percentage growth = ((new value)-(old value))/(old value) x 100%
c) If 20% more utilization is experienced, will the response time increase by more or less than 20%? How much will it increase by?________ %
