Read hit: Line 7
More important than the key write hit is the key read hit. This line indicates the effectiveness of key reads. (Technically, it is the ratio of key reads from hard disk to key reads from RAM.) Key read hit should be no less than 99%. A lower percentage may indicate a problem. A low key hit percentage is usually caused by the key buffer being too small (indicated in the Key Report section above) which prevents MySQL from loading more indexes into RAM. When this happens, MySQL must revert to reading indexes from the hard disk which is terribly slow and completely negates the point of indexes.
It is common, however, for this value to be less than 99% within the first hour or two of starting (or restarting) MySQL. After an hour or two it should definitely be at least 99%.

读取命中：7线
比这更重要的关键的关键是读写击中击中.这表明效力的关键读.（技术上,它是比关键内容从硬盘读取内存的关键.）关键读打不应少于99%.较低的百分比可能表明一个问题.低调的命中率通常是由关键缓冲区太小（表示在关键报告上面的部分）,防止从加载到内存的多指标.在这种情况下,数据库必须回到阅读指数从硬盘是很慢,完全否定了点指标.
这是常见的,但是,这是小于99%,在一两个小时开始（或重新）.一两个小时后,它应该被至少99%.
