How to start investigating Qlik Sense Performance and address high RAM usage

This article includes two videos that aim to provide guidance for Qlik Sense Enterprise on Windows performance issues and RAM usage concerns. 

Note that even though Qlik Sense is referenced in the video, both Qlik Sense and QlikView share the Qix engine. This means they share performance aspects and the investigation steps and considerations are the same in many scenarios, or at least very similar.

Common root causes of performance issues and high RAM usage are (but not limited to):

  • System architecture design 
  • Dedicated servers vs. shared 
  • Too many concurrent tasks
  • Live data reloads in task
  • Poorly designed app
  • Large apps
  • User traffic
  • Hardware constraints

  2. Troubleshoot High RAM usage
