How often should dashboards refresh?

Operational dashboards (ops, support): 30-60 second refresh. Executive dashboards: 5-15 minute refresh. Analyst dashboards: manual refresh on demand. Real-time alerts: WebSocket push on threshold breach. Over-refreshing at 5-second intervals for 100 concurrent users = 1,200 queries/minute - likely more than the underlying DB can sustain.

When should you use WebSockets instead of polling for dashboards?

Use WebSockets when: server needs to push changes in < 5 seconds, number of concurrent dashboard sessions is high (polling creates N*refresh_rate queries), or you need true real-time (fraud alerts, trading). Use polling for: < 30-second acceptable latency, simpler infrastructure, and REST-only backends.
