Performance Analysis

See the main article at Performance analysis

Performance analysis, commonly known as profiling, is the investigation of a program's behavior using information gathered as the program executes. Its goal is to determine which sections of a program to optimize.

A profiler is a performance analysis tool that measures the behavior of a program as it executes, particularly the frequency and duration of function calls. Performance analysis tools existed at least from the early 1970s. Profilers may be classified according to their output types, or their methods for data gathering.

Famous quotes containing the words performance and/or analysis:

    Tennis is more than just a sport. It’s an art, like the ballet. Or like a performance in the theater. When I step on the court I feel like Anna Pavlova. Or like Adelina Patti. Or even like Sarah Bernhardt. I see the footlights in front of me. I hear the whisperings of the audience. I feel an icy shudder. Win or die! Now or never! It’s the crisis of my life.
    Bill Tilden (1893–1953)

    Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.
    Joseph Featherstone (20th century)
