Fig. 4.5. Average Latency and Throughput of a 16 node Application Server
The latency and throughput results of the three models (RR, ssl with session and
ssl with bf) in a 16 node application server are plotted in Figures 4.5. The results are
measured as k value decreases from 26 to 18, where k is the parameter of the Pareto
distribution for the incoming request interval, P (x) =  k
/x
 +1
. When k decreases, the
request interval becomes shorter, and consequently the load on the servers increases. The
range of k values is chosen such that the average utilization of the servers lies between
50% to 90%. Beyond this point, since all of the servers overloaded, a load balancing
mechanism among the servers is unnecessary.
