# Load Testing

## Locust
```python
# locustfile.py
from locust import HttpUser, task

class MyUser(HttpUser):
    @task
    def index(self):
        self.client.get("/")
```

## Run
```bash
pip install locust
locust -f locustfile.py --host=http://localhost:8000
# Open http://localhost:8089
```

## Key Metrics
- RPS (requests per second)
- P50/P95/P99 latency
- Error rate
- Concurrent users
