I think we can not really improve those 2 lines because they are needed to get a correct context. But one thing, I already stated, is that the setter method of the columns [1] is called very often and this setter need to get the states of the field to make a proper rendering which leads to calling Record.expr_eval. Maybe [2] is a possible solution or we should cache the states on the cell but then the problem is invalidation of this cache (as usual).
