LiveViews subscribing to PubSub or using timers can receive messages faster than useful, causing unnecessary processing and renders.

• Sliding window: >10 same-name handle_info events within 200ms
• Total count: >20 of any single handle_info type
• Suggests debouncing, throttling, or increasing timer intervals
