bandwidth read的意思|示意

We focus on disk reads rather than disk writes, because the majority of disk accesses are for read operations, and the majority of disk bandwidth is used for read operations.

我们关注的是磁盘读取，而不是磁盘写，因为大部分磁盘访问都是为了进行读取操作，且大部分磁盘带宽也用于读取操作。

So, the user can read several article synopsis items on one page, and the server bandwidth is spared from building huge pages even if the user doesn't read it all.

因此，用户可以在一个页面中同时阅读几篇文章的概要内容，并且构建大量的页面会使服务的带宽不够，虽然用户并不会同时访问所有的页面。

To minimize global bandwidth consumption and read latency, HDFS tries to satisfy a read request from a replica that is closest to the reader.

副本的选择，为了降低整体的带宽消耗和读延时，HDFS会尽量让reader读最近的副本。

Many large databases are available to general users in read-only mode, with limited bandwidth or processing time.

许多大型数据库以只读模式对一般用户可用，只有有限的带宽或处理时间。

Overall average disk-read bandwidth is 344MB/second over the entire Throughput test.

在整个吞吐量测试中，磁盘读取的平均总带宽为每秒 344MB。

To minimize global bandwidth consumption and read latency, HDFS tries to satisfy a read request from a replica that is closest to the reader.

为了最大限度地减少全局带宽消耗和读取延迟，HDFS试图让读取者的读取需求离副本最近。
