It improves the performance for those speeds. And, there is no effect for the other speeds. For 10M/half and 100M/half, the fast inter frame gap time let the device couldn't use the feature of the aggregation effectively, because the transfer would be completed fastly. Therefore, use the maximum value to improve the effect of the aggregation. However, you may not feel the improvement for fast CPUs, because they compensate for the effect of the aggregation.
