This improves the performance characteristics of the system memory cache, and, in turn, the application itself.
这有助于改进系统内存缓存的性能特征，从而提高应用程序本身的性能。
For example, you can retrieve information from a backend system, but rather than copy every possible object from the store to memory, just load small pieces and put them into a cache.
例如，可以从后端系统检索信息，但不将每个可能的对象均从存储区复制到内存中，而仅加载其中的小部分，将其放置在缓存中。
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。
You can control the maximum size of the cache by using the command line option in Listing 1, but note that this maximum size may be constrained by operating system restrictions on shared memory
可以使用清单1中的命令行选项控制缓存的最大大小，但是请注意，这个最大大小可能受到操作系统共享内存限制的约束
Memcached is used by many large sites to cache various objects in a distributed memory system, rather than having to read from disk or a database.
许多大型站点都使用memcached在分布式内存系统中缓存各种对象，这样就不需要从磁盘或数据库读取它们。
This is because Oracle uses a lot of virtual memory, particularly with respect to its System Global Area (SGA), which is used to cache table data, among other things.
这是因为Oracle使用大量的虚拟内存，特别是对于其系统全局区域（SGA），这个区域用于缓存表数据和其他东西。
A web server's underlying operating system will cache files that were recently read from disk in physical memory.
Web服务器的基本操作系统将在物理内存中缓存最近从磁盘读取的文件。
You'll have to decide if the trade-off is worth it because the Cache object automatically discards least-used data if the system runs low on memory.
您必须权衡利弊，因为如果系统内存运行效率低，Cache对象会自动丢弃最少使用的数据。
No modern web system runs without a cache, which is an in-memory store that holds a subset of information typically stored in the database.
现在所有的系统有在使用缓存，即在内存中开辟一块区域来存放数据。
When you enable System cache mode on a computer that USES Unified Memory Architecture-based video hardware or AGP, you may experience a severe and random decrease in performance.
当您启用的计算机上使用统一内存架构的系统缓存模式视频硬件或AGP，您可能会遇到严重的性能和随机下降。
Each pod has its own processors and memory, and is connected to the larger system through a cache-coherent interconnect bus.
每个pod具有自己的处理器和内存，并通过一条高速缓存一致性互连总线(cache - coherent interconnect bus)连接到较大的系统。
No modern web system runs without a cache, which is an in-memory store that holds a subset of information typically stored in the database.
缓存对现代Web程序不可或缺，缓存是从数据库取回，并存放在内存中的数据。
Cache as much as possible. Use memcached - memcached is a high-performance memory object caching system intended to speed up dynamic web applications by alleviating database load.
尽量做缓存，可使用memcached . memcached是一款高性能的内存对象缓存系统，可用来加速动态Web应用程序，减轻数据库负载。
The target processor can access data in the cache more efficiently than it accesses data in the system memory.
目标处理器能够比访问系统存储器中的数据更有效率地访问高速缓存中的数据。
This removes the schema from the in-memory schema cache, but not from the file system.
该操作将从内存中的架构缓存中移除架构，但不从文件系统中移除架构。
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。
