App Performance Optimization - Best Practices

[ChaithraMahesh]

To keep dashboards fast:

• Limit the number of visualizations per sheet
• Avoid heavy calculations in UI - push logic to script
• Use set analysis instead of complex IF conditions
• Avoid high-cardinality fields (like timestamps) in charts
• Use aggregation wisely (e.g., Aggr() only when needed)

In my experience, these points are very relevant, especially when working with large apps or dashboards used by many users.
