# Performance Tuning

## WASM Fuel

Increase fuel for CPU-intensive agents:

```yaml
agents:
  analyzer:
    wasm:
      fuel: 5000000
```

## Memory

Increase memory for data-heavy agents:

```yaml
agents:
  analyzer:
    wasm:
      memoryPages: 512
```

## Database

Enable WAL mode for better concurrent performance:

```yaml
advanced:
  walMode: true
```

## Pool Sizing

Right-size pools based on workload:

```bash
naos pool status workers
# If queue is consistently > 10, scale up
naos pool scale workers --size 10
```
