Improving response time by caching rules with the Static Assembler

The Static Assembler allows you to pre-assemble and cache the rules of an application. Such pre-assembly is optional, but improves the response time for interactive users after system startup, especially after new ruleset versions are imported into a system, many rules have changed, or user profiles have changed to allow new or different ruleset versions.

To access the Static Assembler landing page, click Configure > System > Assembly > Static Assembler.

To assemble an application, select the application from the list available in the Application Name drop-down control.

Click Start Assembly to begin processing. The page changes to show progress. Processing may take several minutes or more, depending on the size of the application and other system demands.

Click Stop Assembly if you want to abandon this process. No assembled rules are retained.
