6: Best Practices for AEM Content Sync

6.1 Optimizing Performance

Tips for Ensuring Efficient and Effective Content Synchronization

  1. Use Incremental Sync:
    • Implement incremental synchronization to update only the changed content rather than syncing the entire repository. This reduces data transfer and improves sync speed.
  2. Optimize Content Size:
    • Compress large files and images to reduce their size without compromising quality. Use efficient formats and resolutions appropriate for mobile devices.
  3. Leverage Caching:
    • Utilize caching strategies to store frequently accessed content locally. This minimizes the need for repeated data transfer and enhances performance.
  4. Prioritize Essential Content:
    • Sync high-priority content first to ensure users have immediate access to critical information. Defer less important content to subsequent sync operations.
  5. Schedule Sync Operations:
    • Schedule synchronization during periods of low network activity, such as overnight or during off-peak hours. This ensures faster sync times and reduces server load.
  6. Monitor and Optimize Network Usage:
    • Implement network usage monitoring to track data transfer rates and identify bottlenecks. Optimize sync algorithms based on network conditions to ensure smooth performance.

Importance of Regular Updates and Maintenance
