Task OptimizationsRelationship Tabs and PerformanceBecause of the number of security evaluations Identity Manager performs,rendering a relationship tab can significantly impact performance. The factorsthat determine performance vary depending on the type of tab.For role relationship tabs, the following factors can impact performance:■■■■■■Number of roles where the task's subject is a memberNumber of roles where the task's subject is an administratorNumber of total objects in the system that Identity Manager requires tocalculate the subject's rolesNumber of member/admin policies per roleComplexity of the member/admin policy scope rulesThe ability to maintain cached authorizations for the task invokers to limitthe effect of the security enforcementsTo determine group membership and administrative privileges on grouprelationship tabs, Identity Manager must search all of the groups in the userstore. Performance of these searches depends on the following factors:■■■Number of group objects in the user storeNumber of members in any groupPerformance of the database or directory where the user store exists80 Implementation Guide
