Your real slowdown is probably from the number of Droppables which
must be checked on each mousemove. Various solutions (Peter will
point out he "doughnut" concept) have been proposed, but none are
part of the scriptaculous core.
So far as lazily creating Draggables: some on this list create them
on mouseover, which works nicely. In the past I've even waited until
the mousedown, but that requires an extra bit of coding to
immediately kick-start the draggable:
onMouseDown: function (event) {
var d = new Draggable('someDivId');
//You'll need to add these two lines to start a draggable if
mouse is already down
d.initDrag(event);
Draggables.updateDrag(event);
}
