我们想使用 SonarQube 5.1.1 来分析一个包含大约 25.000 个文件的 Java 项目。但是“应用项目排除”步骤非常慢，需要 2.5 小时。同时，AIX-DB-Server 上的 CPU 活动非常高 - 60% CPU。
在 TRACE 模式下启动 SonarQube-Analysis (ANT-Task) 时，我们可以看到，以下 SQL 的执行速度非常慢。每个 SQL 大约需要 0.5 秒。看来，这个 SQL 是为 25.000 个文件中的每一个执行的。
我不是 Oracle 专家，但问题似乎是对 25.000 个文件中的每个文件的“project_measures”表上的“全表扫描”。
关于变通办法或解决方案的任何想法？
我不确定这是否是同一个问题：sonarqube-apply-project-exclusions-very-slow
