Avoid Unnecessary Queries

Displayr queries data. The more queries that are requested, the slower Displayr can become. Occasionally Displayr is used in ways that cause many more queries than you may be aware are occurring. The following are "expensive" queries that can sometimes be avoided:

• Reducing page clicks. When you click on a page in Displayr it causes the results on a page to be recomputed. Two non-obvious ways that this can cause problems are:
  • Filling in time while waiting for a document by randomly clicking on pages. This just guarantees you wait longer.
  • Working with a colleague who randomly clicks on pages.
• Exporting (e.g., to PowerPoint), as this will cause each page to be clicked on in the background.
• Encouraging heavy usage in View mode. If you have a large number of users and they are doing more computationally expensive actions, such as filtering or using Explore mode, this will use up more resources and, at some point, this will affect users. However, the effect of multiple users in View mode is relatively minor (having 50 or more users interacting at the same time should not be a problem).
