Open-source consulting firm KDAB has released Hotspot 1.3 as their GUI utility for visualizing Linux perf reports.

Hotspot is a utility for consuming data generated by Linux's perf subsystem and serves as a replacement to the command-line perf report functionality.

Hotspot 1.3 brings improvements for dealing with large and complex perf.data files, it is much faster than previous releases, and also properly supports perf analysis data that has been compressed using Zstd. On the user-interface side the Qt application has improved timeline handling, support for demangling rustc symbols, and a variety of smaller improvements.

Those wanting to learn more about Hotspot 1.3 can visit KDAB.com. The code is open-source under the GPL on GitHub.
