        $(document).ready(function() {
                var data = [];
                var columns = [];
                var rowdata = [];

                for ( var i=0 ; i< 200 ; i++ ) {
                    columns.push({ title: "Title" + i });
                    rowdata.push(i);
                }
                for ( var i=0 ; i< 5000 ; i++ ) {
                    data.push(rowdata);
                }
                 
                $('#example').DataTable( {
                    data:           data,

                    deferRender:    true,
                   // scrollX:        true,
                    scrollY:        200,
                    scrollCollapse: true,
                    scroller:       true,

                    columns: columns
                } );

        } );

the vertical scrolling performance is very poor

The deferRender option works for rows only, as the documentation for that option describes. There is unfortunately no option to virtualise the column rendering at this time.
