  Solution:
  
  No Immediate Action Required: Since this message is informational, there is typically no immediate action required unless you are experiencing performance issues.
  Performance Optimization: If you notice that the time taken (indicated by &1 ms) is excessively high, you may want to investigate the performance of the backend service or the efficiency of the filtering logic in your application.
  Monitoring and Logging: Keep an eye on the logs for any recurring patterns or performance bottlenecks. If the time taken is consistently high, consider optimizing the backend queries or the data model.
  Caching Strategy: Review your caching strategy to ensure that it is effectively reducing the load on the backend while still providing timely updates to the UI.
  
  Related Information:
  
  SAPUI5 Documentation: Refer to the official SAPUI5 documentation for more details on caching mechanisms and performance optimization techniques.
  SAP Community: Engage with the SAP Community forums to see if other developers have encountered similar messages and how they addressed them.
