Program Memory Usage: Address Space Data

Address space data represents the process address space as a series of segments, each of which contains a number of pages. It allows the Sampling Analyzer to describe the status of each page and whether it was referenced or modified. Program memory-usage data can be displayed in the Sampling Analyzer in the Address Space display.

Address space data helps answer the following kinds of questions:

• How does memory usage change over time?

• Is the application using pages efficiently?

• Which pages are accessed during a particular operation?
