KCachegrind is a browser for data produced by profiling tools.KCachegrind features various visualization views for a selected function, namely

• a call-graph view, which shows a section of the call graph around the selected function,
• a tree-map view, which allows nested-call relations to be visualized, together with inclusive cost metric for fast visual detection of problematic functions,
• source code and disassembler annotation views, allowing to see details of cost related to source lines and assembler instructions.

KCachegrind is part of the KDE SDK package, and it is released at the same time as the rest of KDE SDK and KDE.
