How to improve Tableau Pulse performance

For example, for the metric "Revenue", the metric filters that are interesting to Sales vs Marketing vs Prod Mgmt can be different. So instead of one MD that contains ALL of the metric filters, create a Revenue MD for Sales (with an MD Filter of Dept=Sales) with those specific metric filters and another Revenue MD for Marketing (with an MD Filter of Dept=Marketing) with those specific metric filters, etc.

However, performance is going to be a function not only of the # of those adjustable metric filters but also of the # of unique dimension values. For example, a "Region" dimension (North, East, South, West) would have less of an impact on performance than "State" (Alabama, Alaska ... Wyoming) which would have less of an impact on performance than "City" (New York, LA, Miami ... etc.)
