TableView slow to redraw

I'm using tableView_willDisplayCell_forTableColumn_row to color the text in all cells of the rows of a table (eight columns) where a checkbox on that row is checked. Works great. Except that as the TableView is resized larger it takes longer to redraw the table. Perhaps obviously. But I mean it takes noticably longer--two seconds or so if the window containing the table is full screen. I can almost live with that. But the annoying thing is that the window needs to redraw quite often, such as when re-sorting by column, or when a utility window is opened or closed over it, or when the app becomes/resigns active, and so on.

The code for the method looks like this:


on tableView_willDisplayCell_forTableColumn_row_(aTableView, aCell, aColumn, aRow)
	if (aColumn's identifier()) as text is not "tCheckbox" then
		if (arrayController's arrangedObjects())'s objectAtIndex_(aRow)'s tCheckbox is true then
			if ((aCell's isHighlighted()) as boolean is true) then
				aCell's setTextColor_(whiteColor)
			else
				aCell's setTextColor_(grayColor)
			end if
		else
			aCell's setTextColor_(blackColor)
		end if
	end if
end tableView_willDisplayCell_forTableColumn_row_


Is redrawing slower because things are happening asynchronously with ASOC? Or something like that? Is there anything I can do to liven things up? I like the text-coloring effect, but I'm prepared to lose it if I can't keep it speedy.
