Still there is a performance regression somewhere and while the C++
solution is most performant the cause of this regression can hit other
parts of Qml stack.
Ekke do you use prebuilt binaries or do you compile them yourself?
If you compile yourself you can bisect and find the cause. Not many
patches landed in qtdeclarative in 5.11.3:
4a886753a Accessible: Return StaticText if there is no explicit role set

Thanks, Thiago for the hint - that was the first thing I tried, but
couldn't figure out HowTo make it work on Android and iOS.
unfortunately now with 5.12 Beta it slows down by 20x.
Then get a 400x improvement by trying the C++ part again. OpenSSL is easy on
Android, since you'll have to deploy it anyway alongside your application.
On iOS and macOS, you shouldn't use OpenSSL. You should use Apple's API,
whatever it is. Please consult Apple's website.
