特别是当节点加入网络之前服务已经启动时，除了控制报文大小的变化以外，不会造成额外的控制开销。

Especially no additional cost exists if services have started before the network topology is formed, except the size of control packets grows.

比较案例3和6可发现，取决于报文的大小，相同的设置可能导致从1.8到7 GB的不同吞吐量。

Comparing cases 3 and 6 shows that identical setups might result in throughputs from 1.8 to 7 GB, depending on the message size.

由于每个事务都有一个基本的开销，如果报文的平均大小较小(例如10 KB)，那么事务持续时间不会显著减少。

As there is a base overhead per transaction, a smaller average message (10 KB, for instance) will not reduce the transaction duration significantly.
