+```
+
+### Database/Cache (Optional)
+
+For scaling, add Redis for caching:
+
+```yaml
+# In docker-compose.yml
+redis:
+  image: redis:7-alpine
+  ports:
+    - "6379:6379"
+  volumes:
+    - redis_data:/data
+
+volumes:
+  redis_data:
+```
+
+### Backup Strategy
+
+```bash
+# Backup model cache
+tar -czf quran-models-backup.tar.gz ~/.cache/huggingface/
+
+# Upload to S3
+aws s3 cp quran-models-backup.tar.gz s3://your-bucket/backups/
+```
+
+## Performance Tuning
+
+### Environment Variables
+
+```env
+# Reduce memory footprint
+COMPUTE_TYPE=int8
+
+# Optimize processing
+WORKERS=1
+TIMEOUT=300
+
+# GPU Configuration
+CUDA_VISIBLE_DEVICES=0,1  # Multiple GPUs
+
+# Logging
+LOG_LEVEL=WARNING  # Reduce logging overhead
+```
+
+### Load Testing
+
+```bash
+# Install locust
+pip install locust
+
+# Create locustfile.py
+# Run tests
+locust -f locustfile.py -u 10 -r 1 --headless -t 1m
+```
+
+## Troubleshooting
+
+### Out of Memory
+
+```bash
+# Reduce workers
+WORKERS=1
+
+# Use smaller compute type
+COMPUTE_TYPE=int8
+
+# Check memory usage
+free -h  # Linux
+Get-Process | Sort-Object WorkingSet64 -Descending | Select -First 10  # Windows
+```
+
+### Slow Requests
+
+```bash
+# Check GPU utilization
+nvidia-smi
+
+# Check CPU
+top  # Linux
+Get-Process | Where-Object {$_.Handles -gt 900} | Sort-Object Handles  # Windows
+

+
+## ⚡ Performance Tips
+
+### For Faster Processing
+
+If you have an NVIDIA GPU:
+1. Ensure CUDA is installed
+2. Make sure `.env` has `CUDA_VISIBLE_DEVICES=0` (or your GPU number)
+3. The API will automatically use GPU (check logs: "Loading model... on cuda")
+
+### For Limited Resources
+
+If you have limited RAM/storage:
+1. Edit `.env` and set: `COMPUTE_TYPE=int8` (smaller, still accurate)
+2. Ensure you have at least 4GB of available RAM
+
+## 🆘 Troubleshooting
+
+### Model Download Fails
+- Check your internet connection
+- Make sure you have 500MB free disk space
+- The model will download on first run
+
+### "Port already in use" Error
+```bash
+# Use a different port
+uvicorn main:app --port 8001
+```
+
+### Out of Memory Error
+```env
+# In .env, change:
+COMPUTE_TYPE=int8
+```
+
+### GPU Not Detected
+```bash
+# Check GPU availability
+python -c "import torch; print(torch.cuda.is_available())"
+
+# If False, use CPU:
+# In .env, set:
+CUDA_VISIBLE_DEVICES=
+```
+
+## 📚 Next Steps
+
+1. **Read the full documentation**: Open [README_COMPLETE.md](README_COMPLETE.md)
+2. **View API examples**: See [client_examples.py](client_examples.py)
+3. **Deploy to production**: Follow [DEPLOYMENT.md](DEPLOYMENT.md)
+4. **Integrate with frontend**: Check JavaScript examples in [client_examples.py](client_examples.py)

+| 1 minute | ~2-3 seconds | ~10-20 seconds |
+| 5 minutes | ~8-12 seconds | ~40-60 seconds |
+
+*Actual times may vary based on hardware and audio quality*
+
+## 🐛 Troubleshooting
+
+### Model Download Issues
+
+If the model fails to download from Hugging Face:
+
+1. Check internet connection
+2. Set Hugging Face cache directory:
+   ```bash
+   export HF_HOME=/path/to/cache
+   python main.py
+   ```
+
+### CUDA/GPU Issues
+
+If GPU is not detected:
+```bash
+# Check CUDA availability
+python -c "import torch; print(torch.cuda.is_available())"
+
+# Set to CPU mode
+export CUDA_VISIBLE_DEVICES=""
+uvicorn main:app
+```
+
+### Out of Memory Error
+
+Reduce batch size or use CPU:
+1. Set `COMPUTE_TYPE=int8` for smaller memory footprint
+2. Use `CUDA_VISIBLE_DEVICES=""` to switch to CPU
+3. Reduce `WORKERS` in `.env`
+
+### Slow Transcription
+
+1. Check if GPU is being used: `nvidia-smi`
+2. Use `float16` instead of `float32`
+3. Ensure sufficient GPU VRAM (6GB+ recommended)
