最近、JBoss 7.1.1Final に J2EE アプリケーションをデプロイしました。このアプリケーションは、CDI (Weld 実装)、JSF 2.1 (Mojarra)、Seam 3、および Hibernate 4 を使用しています。負荷が高くなると、アプリケーションが遅くなります。負荷が少し下がっても応答性は悪いままです。CPU 使用率は、8 コア マシンで約 300% です。ということで、CPUがボトルネックではないようです。また、データベースまたは IO がボトルネックである可能性があるかどうかも確認しますが、そうではありません。十分なメモリもあり、JVM は提供された 3GB のうち最大 2GB を使用します。他にどこを見るべきか本当にわかりません。サーバーの CPU 使用率が高い場合、CPU を最も使用しているスレッドをダンプしました。Weld または JSF のいずれかに問題があるようです。応答性が低い場合に頻繁に発生するスレッド ダンプの一部を次に示します。
