 - Both the ALIGNED mode and DEBLOAT modes demonstrate a strong throughput on the Arm64 VM.  
 - The benchmark confirms that the Arm64 architecture efficiently handles Flink's remote channel throughput workloads.  
-- Overall, the average throughput across both modes is approximately **14,854 ops/ms**, indicating strong baseline performance for Arm64deployments.
