Sun Java System Web Server 7.0 Update 3 Performance Tuning, Sizing, and Scaling Guide

Dynamic Content Test: NSAPI

The NSAPI module used in this test was It prints the NSAPI environment variables along with some text to make the entire response 2 KB. The goal was to saturate the cores on the server and find out the respective throughput and response time.

The only tuning for this test was optimizing the path checks in obj.conf by removing the unused path checks.

The following table shows the results of the dynamic content test for NSAPI.
