We have developed a toolkit that collects performance measurements of fully-optimized executables using sampling, analyzes application binaries to understand the structure of optimized code, correlates measurements with program structure, and presents the resulting performance data in a top-down fashion to facilitate rapid analysis.

1. A top-down calling-context view associates an execution's dynamic calling contexts with their costs. Using this view, one can see how much of the application's cost was incurred by a function when called from a particular context.
2. A bottom-up caller's view enables one to look upward along call paths. This view is useful for understanding the performance of software components or procedures that are called in more than one context.
3. A flat view organizes performance data according to an application's static structure. All costs incurred in any calling context by a procedure are aggregated together in the flat view. The flat view shows the detailed breakdown of a procedure's cost among its loops, source lines, and inlined code.
