I notice your just using the filtering capabilities of the RadComboBox, but have settings set for LoadOnDemand and you're not using the LoadOnDemand feature. So basically you're loading all the items and filtering them on the client-side, which is why it takes so long. I would suggest using the LoadOnDemand capability of RadComboBox.

This demo should help:

I hope that helps.
