「当社ではサービスのスケーラビリティを向上させる取り組みの一環として Stackdriver Profiler を利用しました。これにより、CPU 時間を最適化してコストを削減できる箇所を特定できるようになり、非常に役に立ちました。」 —Evan Yin 氏、Snap のソフトウェア エンジニア
「Stackdriver Profiler によって、コード内のどこが非常に遅いのかを特定できました。巨大で複雑なバッチ プロセスの中に隠れていたのです。日々、何百ものバッチを実行しており、それぞれデータセットや設定が異なるため、クライアント固有の設定に関するパフォーマンスの問題を追跡することは難しいのですが、Stackdriver Profiler のおかげでとても助かりました。」 —Nicolas Fonrose 氏、Teevity の CEO
