When using the AQ_Statistic_Process container in combination with the AQ_Statistic_Visualization container you might experience performance problems when using a large number of cases/aggregates. The performance impact depends on:

• the number of cases or aggregates
• the number of times the AQ_Statistic_Visualization container is displayed
• the number of concurrent users
• how many cases match the criteria defined in the AQ_Statistic_Process container 
• how many criteria are defined in the AQ_Statistic_Process container. 

...

• slow loading time of pages containing one or more AQ_Statistic_Process containers
• overall decrease of performance
• memory usage spikes on the server while rendering pages containing one or more AQ_Statistic_Process containers

The memory usage spike is per user session. If the affected pages can be viewed in multiple concurrent user sessions (i.e. not just by an "administrator" user) the memory usage increase should be multiplied by the number of concurrent user sessions rendering the affected pages. 

Solution

It is recommended to avoid the following situations:
