What can be done to optimize application performance regarding rule caching?

Optimizing application performance regarding rule caching can significantly impact the speed and efficiency of a Pega application. Removing branch rulesets from production is an effective strategy because branch rulesets can introduce added complexity and overhead for the system when searching for rules.

When a system checks for rules, it must evaluate all available rulesets in a specific order. Branch rulesets can diverge from the mainline of development and may not be necessary in the production environment. By eliminating these branch rulesets that are no longer used or are irrelevant, you streamline the rule resolution process, which can enhance the performance of the application.

Reducing the number of rulesets that the application needs to traverse means that the rule caching mechanism can function more efficiently, reducing overhead and improving response times for users. Therefore, optimizing rule caching by removing unneeded branch rulesets is a strategic approach that helps maintain a more efficient rule resolution process in a Pega application.
