Which setting should be enabled to improve cache performance for reports?

Enabling the auto-cache setting significantly enhances cache performance for reports. When this feature is activated, the FortiAnalyzer optimizes the storage and retrieval of frequently accessed report data. By utilizing caching, the system can quickly deliver results without needing to access the underlying logs each time a report is generated. This leads to faster report generation times, reduced load on the database, and an overall improvement in performance during data retrieval.

In contrast, while log aggregation, auto-log deletion, and cache compression can contribute to the overall efficiency of log management and storage, they do not specifically target the improvement of cache performance for reporting. Log aggregation combines multiple logs for efficient management but does not directly impact caching. Auto-log deletion helps manage storage but does not enhance cache performance. Cache compression may reduce the storage footprint of cached data but does not inherently speed up access to that data. Thus, enabling the auto-cache setting is the best choice for optimizing report performance.
