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
Enable snaps on Raspberry Pi and install KCachegrind
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Enable snapd
On a Raspberry Pi running the latest version of Raspbian snap can be installed directly from the command line:

sudo apt install snapd
You will also need to reboot your device:
sudo reboot
After this, install the snapd snap in order to get the latest snapd:
sudo snap install snapd
