+
+## 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]
