是否在控制器动作后使用after_filter，是否会缩短为用户生成最终视图的时间？

Suppose we have an action in the controller where very important to me as soon as you generate the view, which is divided into the part where we generate the view for the user and the part that processes certain information, but has no relation with a view.
