TitleThe response time of QList view is high in lists with large number of records
CauseThis is a product defect
Possible work around for this defect:
If a list has 5000 items, the ID of the items are from 1 to 5000. By default, the qListView displays the top 2000 items. If you want to see those items from 4000 to 5000, open the ezEdit, in Display tab, add ID column as a Search Field, save the configuration. Then in qListView, set the filter to ID between 4000 and 5000, perform the search. It will return the items in that range.
