This tutorial shows the simplest example of profiling with Oracle Developer Studio Performance Analyzer and demonstrates how to use Performance Analyzer to collect and examine a performance experiment. You use the Overview, Functions view, Source view, and Timeline in this tutorial.
The program lowfruit is a simple program that executes two different tasks, one for initializing in a loop and one for inserting numbers into an ordered list. Each task is performed twice, in an inefficient way and in a more efficient way.
The data you see in the experiment that you record will be different from that shown here. The experiment used for the screen-shots in the tutorial was recorded on a SPARC T5 system running Oracle Solaris 11.3. The data from an x86 system running Oracle Solaris or Linux will be different. Furthermore, data collection is statistical in nature and varies from experiment to experiment, even when run on the same system and OS.
The Performance Analyzer window configuration that you see might not precisely match the screen shots. Performance Analyzer enables you to drag separator bars between components of the window, collapse components, and resize the window. Performance Analyzer records its configuration and uses the same configuration the next time it runs. Many configuration changes were made in the course of capturing the screen shots shown in the tutorial.
This tutorial is run locally on a system where Oracle Developer Studio is installed. You can also run remotely as described in Using the Remote Performance Analyzer.
