# Get Slowest Operations

`GET /v1/analytics/performance/engine/slow-operations`

Get slowest individual operations.

Returns the slowest profiled operations, useful for debugging
specific slow executions.

**Use Cases:**
- Troubleshoot specific slow operations
- Identify outliers
- Deep dive into problematic executions

**Filtering:**
- `threshold_ms`: Only show operations slower than this
- Default: 1000ms (1 second)

**Response:**
- Timestamp of slow operation
- Stage name and component
- Latency in milliseconds
- Full metadata context

**Example:**
```bash
GET /v1/analytics/performance/engine/slow-operations?hours=24&threshold_ms=5000
```

## Query parameters

- `hours` integer — Hours of history
- `limit` integer — Number of operations to return
- `threshold_ms` number — Only show operations slower than this (ms)

## Response `200`
