💡 内容: llm_service.py において、感情分析に使用している DistilBERT モデルに torch.quantization.quantize_dynamic を適用し、動的8ビット量子化を導入しました。

🎯 理由: CPU 上での推論レイテンシを削減し、アプリケーションの応答性とスループットを向上させるためです。

📊 影響:

  • 未キャッシュ状態での推論時間が約 24.17ms から約 11.84ms へと短縮されました(50% 以上の改善)。
  • キャッシュ済みのリクエストへの影響はなく、高速な応答(約 0.0005ms)を維持しています。

🔬 検証方法:

  • benchmark_llm.py を作成して量子化前後の推論速度を比較。
  • pytest test_main.py を実行し、量子化後も感情分析の結果(POSITIVE/NEGATIVE)が正確であることを確認。

- `llm_service.py` の `classifier` プロパティ内で `torch.quantization.quantize_dynamic` を適用
- CPU推論時のレイテンシを50%以上削減 (24ms -> 11ms)
- 遅延読み込みとキャッシュの仕組みを維持しつつ、初回実行時の効率を最適化
