In that case maybe they share a common text buffer and just directly write to it and when the buffer is full it can be sent across the network.

在这种情况下，也许他们有一个共同的文本缓冲区直接写入和缓冲区已满时，它可以通过网络传送。

Unless the redo log buffer is particularly full, only one synchronous writes is required per transaction. if piggybacking occurs, there can be less than one synchronous write per transaction.

除非重做日志缓冲区特别满，否则每个事务处理只需要一个同步写入。
