In addition, because the literal block data is stored in memory, little or no massaging of the in-memory data is required before writing it to disk, greatly reducing CPU overhead.
此外，因为文字块数据存储在内存中，这些内存数据在写到磁盘之前，不必或只需作很少更改，大大减少了CPU开销。
If you must deal with many-megabyte XML documents, it's often impractical to spend the memory, disk space, and CPU overhead to manipulate such huge documents.
若必须处理许多兆字节的XML文档，花费内存、磁盘空间和CPU开销来操作这么大的文档通常是不实际的。
A smaller number of changed objects per transaction mean more commits to your database, each of which incurs some disk-related overhead as mentioned in Section 4.5.
每次事务修改的对象数量越少就意味着会有更多数据库提交，正如4.5节所述每次提交都会带来磁盘相关的开销。
There is some CPU overhead in performing the dictionary translation, however there is also an improvement in disk IO efficiency as more data can be retrieved per IO unit.
在执行字典翻译时有一些CPU开销，但是在磁盘IO效率上也有一个提高，在每个IO单元更多数据可被检索。
The reason for this is to limit the amount of dirty pages in memory, which further reduces I/O overhead and disk fragmentation.
这么做可以限制内存中 “脏”页面的数量，从而进一步减少I/O开销和磁盘碎片。
The closer the ratio is to 100 percent, the lower the frequency of disk I/O, and therefore the less overhead of reading data.
命中率越接近 100%，磁盘I/O的频率就越低，因而读取数据的开销就越少。
As a result, the faster the rotational speed, the higher the overhead of disk access.
结果磁盘转速越快，磁盘访问的开销越大。
The proxy cache uses a combination of a memory cache and a disk-based cache to save large amounts of data with little overhead.
