qmlbench | easily benchmark QML/QtQuick

qmlbench is a C++ library. qmlbench has no bugs, it has no vulnerabilities and it has low support. However qmlbench has a Non-SPDX License. You can download it from GitHub.

qmlbench is a tool for benchmarking Qt, QML and QtQuick as a whole stack rather than in isolation. The benchmarks it provides exercise a very large part of Quick, QML, Gui, Core, and as a result can be considered a decent metric for overall Qt performance. As with any benchmarking, if you want reliable results, the first thing you must attend to is ensuring that the system under test is doing the absolute minimum possible. "Typical" operating systems (OS X, Ubuntu, ...) all have a lot of "background noise" in the form of file indexing, automatic updates. All of this should be disabled if possible. You may want to consider disabling networking for the duration of the benchmarking run to help keep things "quiet". In terms of running applications, you should have the bare minimum if at all possible. No email clients, no IRC, no media players. Only your terminal, and qmlbench should be running. If possible (e.g. on Linux), you may want to even look into setting up a custom desktop environment session that doesn't launch anything else (so no gnome-session etc).
