    The DIGITAL Performance and Coverage Analyzer (PCA) is a software
    development tool that helps you analyze the performance of
    applications programs. It can measure, among others, where your
    program spends its time, where it page faults, where it performs
    I/O. It can also measure test coverage so you can tell which
    codepaths in your program are or are not executed by a given set
    of tests.

    PCA consists of two components:

    o  The Collector;

    o  The Analyzer;

    The Collector gathers performance and coverage data from a
    running program and writes that data to a performance data file.
    The Analyzer processes and displays that data in the form of
    histograms and tables.
