The usage scenario fits my needs, that is the reason to evaluate exactly this

I mean - should the QScriptEngine be deprecated, the QQmlEngine/QJSEngine
should also have ways to utilize some form of JIT/preparse. Even in the first
pass where JIT cannot be effective (or when I parse just

I guess you are mostly profiling the JIT compiling, not the actual
evaluation. In order to get realistic results you should keep the
compiled representation of the expression
