This enables you to store and later recover entire objects from the memory cache, instead of reconstructing them by hand within your application.
这就让您可以存储并随后从内存存储恢复全部对象，而不是在您的应用程序内手动重构它们。
The latter option is usually preferable, as it makes less work for the collector and allows the entire cache to be reclaimed with less effort when memory is in high demand.
后一种选项通常更好一些，因为它给垃圾收集器带来的工作更少，并且允许在特别需要内存时以较少的工作回收整个缓存。
Instead, use an in memory hash table to cache the data and just keep a key to the data in the session.
相反地，应该使用内存中的哈希表来缓存数据，并且在会话中保存一个对此数据进行引用的键。
Finally, having extra memory on hand allows the file systems to cache files and metadata in memory.
最后，安装更多内存让文件系统可以把文件和元数据缓存在内存中。
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。
The additional CPUs, amount of level two cache, and memory provided better capacity and response time at specific user loads.
额外的CPU、二级缓存量和内存，在特定用户负载下可提供更好的容量和响应时间。
If a cache is too big, then it can waste memory in the JVM and could result in low memory conditions or increased paging, both of which result in performance degradation.
如果缓存太大，则会浪费JVM中的内存，并且可能导致内存不足条件或增加内存分页，这两种情况都会导致性能下降。
Identify problems with memory, including low buffer pool hit ratios, catalog cache hit ratios, and package cache hit ratios.
识别内存问题，包括较低的缓冲池命中率、较低的目录缓存命中率和较低的包缓存命中率。
Due to the latency difference between main memory and on-chip memory cache, POWER7 was designed with three levels of on-chip cache (see Figure 1).
由于主内存和芯片级内存缓存之间的延迟差别，POWER 7设计了三种级别的芯片级缓存机制(见图1)。
The other changes are primarily due to dividing up the available memory for necessary caches like the package and catalog cache or adjusting the Settings for short transactions (logging and sorting).
其他更改主要针对将可用内存划分出一些必要的缓存，例如包缓存和编目缓存，或者调整短事务的设置(日志记录和排序)。
Memory impacts the number of client connections and the size of the buffer pool and database cache allocated by the server.
内存影响客户端连接的数量、缓冲池的大小，以及服务器分配的数据库缓存的大小。
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 files can be served from memory cache, then that decreases the average service time, and hence increases the number of connections per second the server can handle.
如果可以从内存缓存中获取文件，就可以降低平均服务时间，因此增加服务器每秒能够处理的连接数。
The package cache sets the amount of database global memory to be used for caching a package's static and dynamic SQL statements.
包缓存器设置数据库全局内存的总量以用于缓存程序包的静态和动态sql语句。
Similarly, as part of acquiring the monitor when entering a synchronized block, local caches are invalidated so that subsequent reads will go directly to main memory and not the local cache.
与此类似，作为获得监视的一部分，当进入一个同步块时，本地缓存失效，使之后的读操作直接进入主内存而不是本地缓存。
If a program reads a single byte in memory, the processor loads the whole cache line that contains that byte into the L2 and L1 caches.
如果一个程序在存储中读到一个单独的字节，处理器就会释放包含字节的所有的缓存线到L2和L1缓存中。
Cache entries can be scoped with the session ID to keep a relationship between the session and the data that is to be kept in memory.
可以使用会话id设置缓存条目的范围，以使会话和要保存在内存中的数据建立关联。
XFS tries to cache as much data in memory as possible, and generally only writes things out to disk when memory pressure dictates that it do so.
xfs设法在内存中缓存尽可能多的数据，并且，通常仅当内存不足时，才会命令将数据写到磁盘时。
And remember that this memory modification will need to trickle down from L1 to L2 cache, and then to main memory.
不要忘了，这时对内存的修改需要先从L1写入l2高速缓存、然后才写入主存。
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。
Memory is the best persistent store for a cache because access time is (practically) instantaneous and RAM is typically plentiful (or cheap to amass).
内存是缓存的最佳持久性存储，因为访问时间(实际上)是即时的并且RAM的容量通常都很大(或者容易聚集在一起)。
Lvmo allows you to change the pbuf, or pinned memory buffers, used for each volume group, and therefore shows and allows control over the memory used to cache volume group data.
可以使用lvmo修改每个卷组的pbuf(即固定内存缓冲区)，可以显示和控制用来缓存卷组数据的内存。
This loading takes a long time both because of network bandwidth overhead and session cache overhead (memory consumption and GC pause) if your Hibernate session is stateful.
这种加载需要很多时间，既有网络带宽的原因，如果Hibernate的会话是有状态的，其中也会有会话缓存的原因(内存消耗和GC暂停)。
The entire amount of memory allocated to all processes, kernel, and file cache is your total working set.
分配给所有进程、内核和文件缓存的总内存量就是您的全部工作区（working set）。
The entire amount of memory allocated to all processes, kernel, and file cache is your total working set.
分配给所有进程、内核和文件缓存的总内存量就是您的全部工作区（working set）。
