Hi,
I'm switching to Qt5 from Gtk3 and I noticed "QApplication app(argc, argv);" takes ~600ms to execute (cold) or ~200ms (subsequent).
That's a lot compared to "Gtk::Application app(argc, argv)" which is ~50ms.

Is it because Qt5's QApplication is always this slow or because it needs to run in its native environment (which would be KDE 5 I guess which is not finished yet)?

Using Ubuntu amd64, intel core i5, lots of RAM.

Can anyone please check how quickly Qt4's "QApplication app(argc, argv)" executes under KDE4?
