Call path profiling is a scalable measurement technique that has been shown to provide insight into the performance characteristics of complex modular programs. However, poor presentation of accurate and precise call path profiles obscures insight. To enable rapid analysis of an execution's performance bottlenecks, the authors make the following contributions for effectively presenting call path profiles. First, they combine a relatively small set of complementary presentation techniques to form a coherent synthesis that is greater than the constituent parts. Second, they extend existing presentation techniques to rapidly focus an analyst's attention on performance bottlenecks.
