SAPUI5 ComboBox Performance Issues



I have the following problem: I need to display almost 5000 items in a ComboBox control (and allow users to use search on that ComboBox).

At first i noticed only 100 items where shown, but after i use SetSizeLimit(5000) that limit disappear. The problem is that when i load the model and try to open the ComboBox it freezes for a long time and behaves weirdly after: if it opens (only sometimes) i am not able to scroll, it closes itself, etc.

What I don't understand is that if this control is not designed to show many items, then which control is, or what does SAP recomends in this matter. It's easy to say, "filter your data before binding such a large model" but doesn't really apply to my app.
