Suggestions to lower the lag for a panel on a viewport?

So I was able to find a way to switch out the sort functions:

// use custom sort functions for different columns
inline function sortArrayByColumn(rowData, columnIndex, comparisonFunction, sortDirection)
{
    rowData.sort(function[columnIndex, comparisonFunction](a, b)
    {
        var colA = a["col" + columnIndex];
        var colB = b["col" + columnIndex];
        return comparisonFunction(colA, colB);
    });

    if (sortDirection)
    {
        return rowData;
    }
    else
    {
        rowData.reverse();
        return rowData;
    }
};

I store the sort functions in an array and pass them here as "comparisonFunction".
