LvChenhui commented on issue #1372: transientStorePoolEnable开启后rt变高 URL: https://github.com/apache/rocketmq/issues/1372#issuecomment-522392881 > 简单点描述，开启TransientStorePool后，master写入变成 先写堆外内存 ，然后批量commit到 FileChannel写入，而主从同步判断能同步到的消息是已经commit到FileChannel的消息，而消息由堆外内存commit到PageCache是有一定频率的，是受commitIntervalCommitLog，commitCommitLogThoroughInterval两个参数影响，默认值是200ms，所以你能看到消息大体都落在100ms-200ms之间。 懂了，那么将commitIntervalCommitLog，commitCommitLogThoroughInterval调小，频繁的调教到FileChannel是否对系统产生其他影响
