Do you think that Quick2 has a slower perfomance than Quick1.1 when starting an qml Application

With my computer ，when start a Quick1.1 application（Official example），QDeclarativeView’s Window and qml contents are almost simultaneously displayed，while when start a Quick2.0 application（the same Official example），QQuickView’s Window will displayed faster than qml contents，it takes some time rendering until qml contents displayed。 Do you have the same appearance？
