Great tool that has been really helpful in helping me find unexpected bottlenecks in the codebases I've been working on.

It's easy to use, and pairs beautifully with the unintrusive perf tool, which makes the combination a joy to use.

And, if combined with a codebase opened in QtCreator, you can click on a hotspot in the flamegraph, and it will bring you automagically to the correct file and line in QtCreator, without any explicit linking required between the two programs. I discovered that feature accidentally, and the fact that it just worked seamlessly really impressed me. (Tested on a Debian-based Linux).

A big thanks to KDAB for making this tool available to us!

You are welcome :)

And to people using other IDE/editors - you can configure which one gets opened when you click on a source line from the hotspot settings. QtCreator is just the default (when that is installed).
