And since GCC or clang is producing the machine code instead of the Qt JIT, it has better machine code, so it improves overall performance. But if your app performs well with JIT or interpreted it won't preform preceptively better with the compiler. If your app is small enough that QML overhead doesn't matter then you won't notice any difference. Or maybe your app is network-bound, obviously compiling QML doesn't make the Internet go faster.
