Dimension and measure filters can improve performance. Since either a dimension filter or a measure filter will cause Tableau to generate a query to the underlying data source, which will limit the data that is returned, performance is improved. Simply put, the smaller the returned dataset, the better the performance.
Dimension and measure filters can degrade performance. Since Tableau not only generates queries to the underlying data source in order to display visualizations, but also generates queries to display filters, more displayed filters will slow performance. Furthermore, displayed filters on high-cardinality dimensions can inhibit performance. (A dimension with many members is referred to as having high cardinality.) Consider the example of a filter that displays every customer in a dataset. Performance for such a filter might be slow because...
