Dynamic Content Test: Servlet
This test 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
goal was to saturate the cores on the server and nd out the respective throughput and response
time.
The following table shows the JVM tuning settings used in the test.
