Kcachegrind

KCachegrind is a profile data visualization tool, used to determine the most time consuming parts in the execution of a program.

Features:

• KCachegrind visualizes profiles (i.e. runtime characteristics) of applications in various ways, including call graph visualisations and source/disassembler annotation.
• It can load profiles generated by the cache simulation/call tracer Calltree, a Valgrind tool. Thus, profiling does not need any preparation, can cope with shared libraries and plugin architectures, and does not influence the measuring itself.
• Converter scripts for OProfile, Perl, and PHP.
• Switching between multiple visualization layouts.
• Call graph can be exported as image (PNG).
• Simultaneous display of 2 event types in Call and Annotation View
