Hotspot - the Linux perf GUI for performance analysis

This project is a KDAB R&D effort to create a standalone GUI for performance data. As the first goal, we want to provide a UI like KCachegrind around Linux perf. Looking ahead, we intend to support various other performance data formats under this umbrella.

Visualize Data

The main feature of hotspot is visualizing a perf.data file graphically.
