要求磁盘I/O 的事务，例如刷新缓冲池中的脏页或者刷新日志缓冲区中的日志，可能需要等待。
Most often, you want only a small subset of the data in the table, so a full table scan wastes a lot of disk I/O and therefore time.
通常来说，您可能只希望获得表中数据的一个子集，因此全表扫描会浪费大量的磁盘I/O，因此也就会浪费大量时间。
Unlike the tuning of other subsystems, tuning disk I/O should actually be started during the architectural phase of building your systems.
与其他子系统的优化工作不同，实际上在构建系统的体系结构设计阶段就应该开始进行磁盘I/O 优化。
There are many other areas of investigation, for example, hardware, disk I/O, configuration, topology, tuning parameters, OS, and patches, among others.
还需要调查其他很多方面，比如硬件、磁盘I/O、配置、拓扑、调优参数、OS和补丁等。
Redo Logfile Sizing Advisor - This feature recommends the optimal size of redo log files in order to avoid excessive disk I/Os due to frequent checkpointing.
RedoLogfile SizingAdvisor ——此特性推荐重做日志文件的最佳大小，从而避免因频繁出现的检查点而导致过多的磁盘I/O。
Part 3 of this series focuses on the application layer as you move on to file systems, using various commands to monitor and tune your file systems and disk I/O subsystems.
