It happens when the number of droppable elements is big.
1.Maybe you can try to minimize the no. of droppable by setting them
in a dynamic way. (maybe by setting a listener 'mouseover' on your
current droppable elements and every time you drag element over then
set the droppable (only for the current element/ or set of elements).
2.Maybe you could group droppable by hours and then enable/disable
them based on the draggable position?

There are a lot of draggable items, and even more droppable areas on
the page. If I reduce these down to very few, the page runs nice and
quick, but with all the elements I need on the page (there will
probably need to be even more in the future) it is very very slow.
Using firebug profile, I am making in excess of 35000 calls to drag a
single item, whereas with only one draggable and one droppable element
on teh page, that is way down to around 3000. I don't know what
numbers I should expect to be seeing, but I do know the app is too
slow to use in it's current state.
