How many roles should be set as default for better performance in Partner Community or Customer Community Plus user licenses?

Setting one role as the default for better performance in Partner Community or Customer Community Plus user licenses is optimal because it simplifies and streamlines access control and permissions management. By designating a single default role, the system can process user access and permissions more efficiently, reducing potential complexities that arise when multiple roles are involved.

When multiple roles are set as default, it can lead to confusion or conflicts regarding what permissions are applicable, which can negatively impact both user experience and system performance. A singular default role ensures that users have a clear and direct set of permissions applicable to their role, promoting faster data retrieval and a more intuitive interaction with the community features.

This strategic approach aligns with best practices for user management in Salesforce, as it maximizes efficiency while maintaining appropriate access controls tailored to the needs of partners and customers within the community.
