If you want to benchmark random file reads, you likely need to ensure that different files are read to avoid caching.
如果希望对随机文件读取进行基准测试，很可能需要确保读取不同的文件，以避免缓存。
If the workload is a read mostly workload, then solutions like caching with optimistic locking work well.
如果工作负荷主要是读取，那么诸如使用最优锁定进行缓存的解决方案可以很有效。
Caching works best for read-only data.
缓存非常适合于只读数据。
This caching layer optimizes access to the physical devices by keeping data around for a short time (or speculatively read ahead so that the data is available when needed).
这个缓存层通过将数据保留一段时间(或者随即预先读取数据以便在需要是就可用)优化了对物理设备的访问。
Thanks to aggressive caching, opening recently read messages and composing new email will still work fine.
多亏了优秀的缓存功能，用户打开最近阅读的信息和撰写新邮件可以在此类情况下也能工作良好。
The write cache is generally considered to be a very good thing (read Linus' explanation and opinion of write caching in Resources).
通常认为写高速缓存是个非常好的事物(请阅读参考资料中Linus对写高速缓存的解释和看法)。
It offloads the read queries and stored procedures which perform "Select" by dynamically caching in-memory result sets, thereby reducing read response time and overall database load.
它会动态地缓存内存中的结果集，从而减轻执行“Select”操作的查询和存储过程的负载，进而减少读取操作的反应时间以及总体上的数据库负载。
Since each file is read only once, caching is not needed.
由于每个文件只被读取一次，因此缓存完全没有必要。
Since the existing catalog application is immutable, and the catalog items are largely read-only, this is an ideal candidate for the requester-side caching pattern.
由于现有Catalog应用程序不能修改，而 Catalog项目大部分都是只读的，因此这就非常适合采用请求端缓存模式。
You should consider using caching in a web service when the service's requested information is primarily read-only or when that information changes at a slower rate than that at which it is requested.
当服务的请求信息主要是只读的时候或者当那些信息按照比所要求的速率变化得还要慢时，您就应该考虑要在Web服务中使用缓存了。
If caching is enabled, a new background image, either read from CD-ROM or downloaded from the Internet, will be copied to the cache directory.
如果允许使用缓存，当一幅新的图像被读取的时候，它会被自动地复制到缓存目录。
As an alternative to using the default file-based caching mechanism, you can specify a custom cache handling function that will be used to read, write and clear cached files.
一种使用以预设档案为基础的快取机制的方法是定义一个客制化快取处理函式，而此一函式将用来读取、写入、与清除快取档案。
As an alternative to using the default file-based caching mechanism, you can specify a custom cache handling function that will be used to read, write and clear cached files.
作为一种可选择的，使用默认基于文件的缓存机制，你可以定制自定义缓存处理函数用以读、写、清除缓存文件。
