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

SSL Performance Test: NSAPI

The NSAPI module used in this test was printenv2.so. It prints the NSAPI environment variables along with some text to make the entire response 2 KB. The test was performed in SSL mode with the SSL session cache enabled. The goal was to saturate the cores on the server and find out the respective throughput and response time.

The following table shows the SSL NSAPI test results.
