Dynamic ContentTest: Servlet

Thistest was conducted using the servlet. The test prints out the servlet's initialization

arguments,environments, request headers, connection and client information, URL

information,and remote user information. JVM tuning settings were applied to the server. The

goalwas to saturate the cores on the server and nd out the respective throughput and response

time.

Thefollowing table shows the JVM tuning settings used in the test.
