If all the data fits in the cache, then the data is read from disk only once; after that, all requests are satisfied from the cache at memory speed.

If you were to store the data in a real cache, then the system could discard parts of the cache to gain memory for other tasks because the client can always re-create the cached data.
如果要在真正的缓存中存储数据，则系统可能丢弃缓存的部分以获得用于其他任务的内存，这是因为通常客户机可以重新创建缓存的数据。
Storing privately scoped pages in a browser cache is optimal with regard to memory utilization in the cache, as well as in its location as close as possible to the end user.

For example, the architect could create a reusable in-memory cache, to be used in the application when performance needs dictate the need for something like a simple cache.
例如，设计师可以创建一个可重复利用的缓存，当性能需要一个如简单缓存一类的东西时就可以在应用程序中使用。
If you allocate a block of memory on the heap that is not already in the cache, execution will stall while the contents of that memory are brought into the cache.
如果在堆的顶部分配的内存块不在缓存中，执行会在内存内容装入缓存的过程中出现延迟。
TLB cache entry reuse (cache hit) equates to quicker address translation and subsequently faster access to physical memory.
tlb缓存条目重用(缓存命中)意味着更快的地址转换，还意味着对物理内存的更快的访问。
The first is that the Cache implements a least-recently-used algorithm, allowing ASP.NET to force a Cache purge—automatically removing unused items from the Cache—if memory is running low.
首先，缓存会实现最近最少使用的算法，使得 ASP.NET能够在内存运行效率较低的情况下强制缓存清除——从缓存自动删除未使用过的项目。
Because mysqld must perform maintenance on the cache, such as pruning when memory becomes low, the server can get bogged down trying to manage the cache.
由于mysqld必须要对缓存进行维护，例如当内存变得很低时执行剪除，因此服务器可能会在试图管理缓存时而陷入困境。
Therefore, when tuning the cache size for your environment, allocate sufficient in-memory and disk space for the cache entries.
因此，在为您的环境优化缓存大小时，请为缓存项分配足够的内存和磁盘空间。
The cache implemented by the ESI processor is an in-memory cache.
ESI处理器实现的缓存是内存内缓存。
Microprocessor engineers decided to give the cache memory a cache.

This implementation also allows the user to chose between a custom (in memory) user-defined cache or the WebSphere Platform dynamic cache.
这个实现还允许用户选择采用自定义(内存中)的用户定义缓存或WebSpherePlatform动态缓存。
Thus, a write-behind cache gives you memory speed for accessing data on all writes, and for all cache-hit reads, and has other benefits that you will see later.
因此，write - behind缓存在访问所有写入数据以及所有缓存命中读取时都能提供内存速度，而且还有一些其他好处，我们将在下文介绍。
In addition to keeping an in-memory cache of "static" HTML pages, Domino can also cache pages that contain macro language (@function) formulas.
除了在内存中缓存静态HTML页面之外，Domino还能够缓存包含宏语言（@function）公式的页面。
The GPU memory could be considered to be a "cache" of data that the GPU is currently operating on, but many GPU algorithms are designed to operate on more data than can fit in the "cache".
的GPU内存可以被认为是一个“缓存”，GPU目前经营上的数据，但许多GPU算法的设计有更多的数据比操作可以在“缓存”。
The proxy cache uses a combination of a memory cache and a disk-based cache to save large amounts of data with little overhead.
代理缓存采用了结合内存高速缓存和基于磁盘的缓存，以节省大量的数据几乎没有开销。
In this paper, we propose an on-demand mechanism for data cache leakage power management, which manages data cache activities according to the demand of memory accessing instructions.
本文提出面向访问需求的数据缓存泄漏功耗管理方法，根据访存指令对数据缓存的访问需求控制数据缓存的活动。
This text analysis the structure and work elements of cache memory, the procession of cache memory, and the expect to the performance of CPU.
本文分析了高速缓存的结构和工作原理，阐述了高速缓存的工作过程以及对处理器性能的影响。
For example, instead of using the default in-memory cache engine, you can create custom providers that store cache data in databases, in custom objects, or in the file system.
例如，与其使用预设的记忆体中快取引擎，您可以建立将快取资料储存在资料库、自订物件或档案系统中的自订提供者。
