Chapter 41. Performance tuning considerations with Business Central

You can set KIE Server or specific projects in Business Central to use production mode or development mode. By default, KIE Server and all new projects in Business Central are in development mode. This mode provides features that facilitate your development experience, such as flexible project deployment policies, and features that optimize KIE Server performance during development, such as disabled duplicate GAV detection. Use development mode until your Red Hat Decision Manager environment is established and completely ready for production mode.

For more information about configuring the environment mode or duplicate GAV detection, see the following resources:

The decision table verification and validation feature of Business Central is enabled by default. This feature helps you validate your guided decision tables, but with complex guided decision tables, this feature can hinder decision engine performance. You can disable this feature by setting the org.kie.verification.disable-dtable-realtime-verification system property value to true.

For more information about guided decision table validation, see Designing a decision service using guided decision tables.

In Business Central, when you navigate between projects in the Project Explorer side panel, the selected project is built automatically so that the Alerts window is updated to show any build errors for the project. If you have large projects or frequently switch between many projects that are under active development, this feature can hinder Business Central and decision engine performance.

To disable automatic project builds, set the org.kie.build.disable-project-explorer system property to true.
