Qml file and performance

aabc

Does parameters like spaces, comments, new lines etc. on the Qml file impact performance ?

Probably yes, but only when the files are being parsed (at the start of the application). I guess the impact is negligible, but maybe it would be a good idea to check that using a benchmark.

So the qml files arent compiled? It would be interesting to compare the performance of a minimized qml file.

QML, JS are interpretable.

No, they are interpreted when the application starts - after that there is no need to parse them again. In some situations (release builds on non-embedded platforms), the JavaScript code is compiled using JIT.

It is possible to compile QML code, a compiler is available in Qt Commercial Package. It is not available in the Open Source version.
