This study evaluates the performance of 802.3ad and Round-Robin bonding under varying MTU values (450–9200 bytes) across single and parallel stream tests. CPU core utilization and throughput metrics were analyzed to assess efficiency in multi-core systems. Results show that although Round-Robin achieves higher peak throughput in parallel streams, it leads to significant CPU imbalance and potential instability. In contrast, 802.3ad ensures better CPU load distribution and consistent throughput, making it more suitable for long-term, high-performance environments. The study highlights the need for MTU-aware, CPU-efficient bonding strategies in modern, latency-sensitive network designs.}, number={2}, publisher={Çukurova Üniversitesi}
