Sending out a list box with a lot of items to the client is expensive. In addition, the JavaScript engine of the browser is not good for initializing a list box with a lot of items. A better solution is to use the live data, i.e., by assigning a list model to it. Then, the list items are sent to the client only if they become visible.
The performance will be improved more if you also use the paging mold.
Refer to the List Boxes section in the ZK_Component_Reference/Data/Listbox#Live_Data section for more details.
