Consulting firm KDAB has announced their newest research and development project, Hotspot. The Hotspot program is a Qt-powered GUI to the Linux perf subsystem.

With Hotspot it's now more user-friendly to make use of the Linux perf subsystem's various metrics and profiling capabilities via a nice GUI. Hotspot in its public 1.0 form allows a summary view, bottom-up/top-down/caller/callee views, searching, an integrated flame graph, the ability to show multiple event metrics side-by-side, and more.
