Who can change the sizes of Confluence's internal caches?

• A. End users
• B. Space Administrators
• C. System Administrators
• D. Page authors

Answer: (C)

Tuning Confluence’s internal caches is a system-level task. Only System Administrators have the permissions to modify global, performance-related settings in the administration area, which include cache sizes. End users, Space Administrators, and Page Authors operate within their own content-management roles and don’t have access to these server-wide configurations. Changing cache sizes affects memory usage and overall performance, so it’s something that should be done by someone who understands the impact on the JVM and the application, often requiring a restart after changes. In cloud deployments, cache handling is typically managed by Atlassian, with site admins having limited direct control, but the general principle remains that global system access is needed to adjust internal caches.
