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 vizualisations 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
