Analyzing Program Performance With Sun WorkShop

Selecting Data Types for Viewing

The Sampling Analyzer allows you to view different types of collected data. You can specify the kind of data that would help you improve your application's performance.

Select one of the following data types from the Data list box:

Process Times	Summary of process state transitions
User Time	Time spent in the user process state from the execution of instructions
System Wait Time	Time the process is sleeping in the kernel but is not in the suspend, idle, lock wait, text fault, or data fault state
System Time	Time the operating system spends executing system calls
Text Page Fault Time	Time spent faulting in text pages
Data Page Fault Time	Time spent faulting in data pages
Program Sizes	Sizes in bytes of the functions, modules, and segments of your application. Used in conjunction with Address Space data, this lets you examine the size of your application and helps you establish specific memory requirements
Address Space	Reference behavior of both text pages and data pages. Used in conjunction with Program Sizes data, it lets you examine the size of your application and helps you establish specific memory requirements
Execution Statistics	Overall statistics on the execution of the application

Data Types and Display Options

Each data type can be viewed only in displays appropriate to its nature. Table 2-1 lists the display options associated with each data type:
