## 📈 Performance Verification

### Expected Performance (GPU)
- Text embedding: 10-20ms
- Image embedding: 30-50ms
- Model loading: 15-30 seconds
- GPU memory usage: ~4 GB (ViT-L/14)

### Verify Performance
```bash
# Check GPU usage
nvidia-smi

# Check container stats
docker stats dagi-vision-encoder

# Check logs for timing
docker-compose logs vision-encoder | grep "took"
```

---

## 🐛 Troubleshooting

### Problem: Container fails to start

**Check:**
```bash
docker-compose logs vision-encoder
```

**Common issues:**
1. CUDA not available → Check `nvidia-smi` and Docker GPU runtime
2. Model download fails → Check internet connection, retry
3. OOM (Out of Memory) → Use smaller model (ViT-B-32) or check GPU memory

### Problem: Slow inference

**Check device:**
```bash
curl http://localhost:8001/health | jq '.device'
```

If `"device": "cpu"` → GPU not available, fix NVIDIA runtime

### Problem: Qdrant not accessible

**Check:**
```bash
docker-compose ps qdrant
docker exec -it dagi-vision-encoder ping qdrant
```

**Restart:**
```bash
docker-compose restart qdrant
```
