How to fasten QSortFilterProxyModel ?

[Guilo]

Hi !

I am using a QListView and a QLineEdit which filters the QLIstView model with a QSortFilterProxyModel. My model is filled with 8000 rows, one column. But it is quite slow to filter. How to fasten this ? For example in QtCreator when you search for help the filtering is instantaneous whereas there are probably more than 8000 rows.

Thanks
