Filtering a sortedlist in a TableView with 22K rows of data is extremely slow.  It works fine with a few rows.

from javafx forum in OTN https://forums.oracle.com/thread/2589452

private final ObservableList<DataEntry> dataEntries = FXCollections.observableArrayList();
private final FilteredList<DataEntry> filteredDataEntries = new FilteredList(dataEntries);
private final SortedList sl_SortedDataEntries = new SortedList(filteredDataEntries);
private final TableView<DataEntry> dataTableView = new TableView<>();
public static RangeSlider dateRangeSlider = new RangeSlider(0,1,0,1);
 
Then, in my initialize() I set the following
 
dataTableView .setItems( sl_SortedDataEntries );
sl_SortedDataEntries.comparatorProperty().bind(dataTableView .comparatorProperty());
 
dateRangeSlider.lowValueProperty().addListener(new ChangeListener<Number>() {                                                                             >>>> I do this for both the highValueProperty as well
            @Override
            public void changed (ObservableValue<? extends Number> message, Number oldValue, Number newValue) {
                filteredDataEntries.setPredicate( p -> p.getDataEntryInstant().isAfter(Instant.ofEpochMilli(newValue.longValue()))
                        && p.getDataEntryInstant().isBefore(Instant.ofEpochMilli(dateRangeSlider.highValueProperty().longValue())));
     }
});
 
 
If I'm working on a TableView with 22K rows, I can filter the content of the TableView as desired (more or less) if I've not sorted the data.  If the data is sorted, using the slider to filter it takes forever (5-10 min) for the computation to complete.  Doing the filtering in it's own task, obviously takes care of that "app is hung" feeling but the data in the table still takes a while to refresh based on the new predicate.
