Qt Qml - android - adjust listview scroll speed/velocity

[Qt Quick 2.0 (qml) - Android] I searched but I don't get how one can increase the velocity of the scrolling in a listview:

ListView {
    width: 180; height: 200

    Component {
        id: contactsDelegate
        Rectangle {
            id: wrapper
            width: 180
            height: yeah.height
            Column{
               id:yeah
               Text {
                   id: contactInfo
                   text: name + ": " + number
               }
               Image{
                   source: jpgsrc
               }
            }
        }
    }

    model: ContactModel {}
    delegate: contactsDelegate
    focus: true
}

Question

Say my ContactModel has 200 elements. My problem is that the scrolling speed over those elements is too slow. It takes too long to scroll the whole list.

I would like to know how to modify that code to make the scrolling experience faster (at least with a higher velocity).

Thanks

To improve speed of scrolling you can play with 2 ListView properties: cacheBuffer and maximumFlickVelocity.

maximumFlickVelocity directly impacts speed whereas cacheBuffer should be updated if you have speed issues due to slow dynamic loading of ListView elements.
