Performance Hub 是 Oracle Enterprise Manager Database Express （EM Express）中的一项功能，可提供给定时间范围内所有性能数据的新整合视图。用户可以使用 Database Express 页面顶部的时间选择器选择时间范围，详细信息选项卡将显示所选时间范围的可用性能数据。无需登录 Database Express 即可生成此 EM Express 页面，作为名为 Performance Hub Report 的活动数据库报告。
DBA 可以生成和检查活动的实时性能中心报告，该报告将包含有关数据库的整体 IO、CPU 和内存使用情况的摘要信息，并使用 HTML 界面提供清晰的图片。
