Additional performance considerations

To conclude this chapter, let's consider a few other possibilities for improving performance.

Avoid overcrowding a dashboard

Often, end users want to see everything at once on a dashboard. Although this may be perceived as beneficial, it often is not. Consider the inclusion of a large crosstab on a dashboard. Does scrolling through pages of details add to the analytical value of the dashboard? Perhaps, the answer is no.
