27. Performance Tips

27.6 Report Design

  • Keep the number of visuals per page reasonable; each visual sends at least one query.
  • Use drill through and tooltips to show details on demand instead of huge tables on the main page.
  • Limit high-density visuals (tables with thousands of rows, maps with many points).
  • Optimize › Optimization presets can switch on query reduction – e.g. slicers and filters with an Apply button so queries run only once the user finishes selecting.
  • Be careful with heavy custom visuals; test their display time.
  • For DirectQuery, keep the source well indexed, reduce visuals per page and consider aggregations or Dual storage mode for dimension tables.

Ravindra Bagale's Tip

Friends, many students put 25 visuals and 8 slicers on one page and then blame the model. Every visual sends queries, so reduce the visuals per page, use the Apply button on slicers, and move detail tables to drill-through pages. Clear?
