I noticed this while updating to SonarQube 4.5. The documentation and references to this parameter lead me to believe that it is a useful shortcut to optimizing server resources.
In /opt/sonar/sonar.properties
sonar.jdbc.url=jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance
NOTE: In some instances you may need to escape the ampersands!
I’ll change this on a few projects and watch for any issues changes.
