# Live Performance

Open `Live -> Performance` for detailed runtime metrics.

## Core Charts

Performance charts use real Runtime metric buckets and show axes, tooltips, and time-range controls.

Key metrics include:

- Tick performance p50, p95, and p99.
- RTT and jitter.
- Acknowledgement lag.
- Throughput in and out.
- Replication efficiency.
- Backpressure events.
- Reject reason breakdown.

## Regressions

Live compares current performance to a trailing per-deployment baseline. A sustained 25 percent degradation is a warning. A sustained 50 percent degradation is critical.

Regression rows show:

- Severity.
- Current value.
- Baseline value.
- Change percentage.
- Sustained bucket count.
- Recommended action.
- Notification status.

Critical regressions appear in Live immediately. Email delivery for critical regressions is pending the notification hookup listed in the shipped audit.

## Reading A Spike

Use the chart marker and the activity feed together. A one-bucket spike may be noise. Sustained markers usually mean a room, deployment, script, or replication path needs investigation.
