As per my understanding,calculations like Top 10 / Bottom 10 are performance heavy and they are not as fast as other expressions.
Please correct me if I am wrong here ? Also if someone can throw some light on this topic,as what could be the best way to find out Top N / Bottom N views ?
There are several places that Tableau has provided instructing on how to do this.
