## Performance Optimization

### Memory Optimization

```python
# For GPUs with limited VRAM
pipe.enable_attention_slicing()
pipe.enable_vae_slicing()
pipe.enable_sequential_cpu_offload()

# Or use model CPU offloading
pipe.enable_model_cpu_offload()
```

### Speed Optimization

```python
from diffusers import DPMSolverMultistepScheduler

# Use faster scheduler
pipe.scheduler = DPMSolverMultistepScheduler.from_config(
    pipe.scheduler.config
)

# Reduce inference steps
image = pipe(prompt, num_inference_steps=20).images[0]
```

### Quality Optimization

```python
# Use float32 for better quality (if VRAM allows)
pipe = StableDiffusionPipeline.from_pretrained(
    model_id,
    torch_dtype=torch.float32
)

# Increase steps and guidance
image = pipe(
    prompt,
    num_inference_steps=50,
    guidance_scale=9.0
).images[0]
```
