QSortFilterProxyModel sort on mac unoptimized

XMLWordPrintable

    • macOS

      Compared to Windows the sorting on Mac using QSortFilterProxyModel is much slower. Attached will be an application to demonstrate the issue. The application will sort 1000 items and count the calls to lessThan(). On Mac this is around 32756 times, whereas on Windows we have only 6840 calls.
