GitHub user RongtongJin added a comment to the discussion: 一主两从的部署相较一主一从RT增加百倍

> 目前部署方式： 3namserver 3controller 3broker（1主2从）
> 
> broker.conf的配置 flushDiskType=SYNC_FLUSH(同步刷盘） allAckInSyncStateSet=true
> 
> 利用mqadmin的clusterRT和CheckMsgSendRT来进行测试 在一主一从（2 broker）的情况下RT为2ms， 而在一主二从（3broker）的情况下RT高达450ms， 请问为什么在多了一个从节点的情况下RT增加这么多？

另一个从节点与其他两个节点之间是否隔的比较远？可以ping下。
