测试openjpa，无缓存。
My third implementation used a service locator with no cache.
我的第三个实现使用没有缓存的服务定位器。
Caching in this case is worse than useless; because it costs more to put data in the cache to begin with, this sort of application would perform poorer overall than with no cache at all.
在这种情况下，缓存不但没有帮助，反而会更糟；因为它将数据放入缓存需要更多的开销，与没有缓存的情况相比，这种应用程序的性能更加糟糕。
Second, in Figure 2 there are no existing object cache instances.
第二，图2 中不存在现有的对象缓存实例。
Nothing will be saved obviously, but no errors will be given-the application will simply not have a cache in this case.
显然不会保存任何东西，但是也不会报错—应用程序在这种情况下只是不会具有高速缓存。
When the JVM starts up, it looks for a class cache of the name given (if no name is provided, it chooses a default name) and it either connects to an existing cache or creates a new one, as required.
当JVM启动时，它寻找给定名称的类缓存(如果没有提供名称，那么选择一个默认名称)，并按照需要连接现有的缓存或创建一个新的缓存。
MS: No. It is a perfectly viable and very high-performance local-mode cache as well.
MS：不需要。它还是一个可运行在本地模式下的高性能缓存。
Immediate notification of clients; no need to cache events.
直接通知客户端；不需要缓存事件。
Once you've set the initial options and configured the directory and cache size you want, there's no need to change anything.
一旦设置了初始化选项并配置了期望的目录和高速缓存大小，就不需要再做任何改动。
The other option is to iteratively increase the cache size and run the application under peak steady state load until the PMI metrics report no more cache discards.
其一种方法是迭代式的增加缓存大小并在峰值稳定状态负载下运行应用程序，直到PMI指标不再报告任何缓存丢弃操作。
If no matching valid response can be found in the browser cache, the request is sent to the network.
如果未在浏览器缓存中找到匹配的有效响应，将把请求发送到网络上。
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。
There’s no local state except some encrypted cache.
那么除了一些加密过的缓存之外，本地不存留任何状态。
If the user disables the cookie cache in his browser, no user preferences are stored.
如果用户在其浏览器中禁止cookie缓存，则将不会存储用户首选项。
The hibernate block allows you to adjust the cache Settings. (No need to tweak things here unless you are a hibernate expert.)
hibernate块用来调整缓存设置(除非是hibernate专家，否则不要在这里进行任何调整)。
A great feature of the JPA cache is that no coding change is necessary to use them; you just need some configuration properties (like size and object types to cache) in your persistence.xml file.
jpa缓存有一个很好的特性，即使用时不需要任何代码更改；仅需在persistence .xml文件中修改一些配置属性(比如缓存的大小和对象类型)。
After each write test, the test disk was unmounted as a way to ensure that no operations remained in Linux's disk cache.
在每个写测试之后，测试磁盘被卸载，以确保在Linux的磁盘缓存中没有操作。
It is expected that for a system using write behind that all changes are made through the cache and through no other path.
可以预见，采用write -behind的系统，作出变更的唯一路径就只能是缓存。
If no value for either cache expiration or cache scope is contributed by the portlet window, the value from the portlet definition will then be used as the contributing value of the portlet.
如果Portlet窗口没有为缓存过期或缓存作用域提供值，则会将Portlet定义中的值作为该Portlet的提供值。
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。
When you use the private browsing mode, your entire Web session is more secure, since no data is retained in the history or cache.
在你使用这个模式的时候，全部的web会话更安全，因为在历史记录及缓存中不会保留任何数据。
Out of the box, varnishd does not cache a response with a cookie, nor does it honor the Cache-Control directives private and no-cache.
默认情况下，varnishd既不缓存带有cookie的响应，也不遵守cache - Control指令private和no - cache。
Because, by default, all caches have entries, modifying this has no effect unless you delete the cache entries later on in the file.
因为默认情况下，所有的高速缓存都有入口，除非您稍后在文件中删除某些高速缓存的入口，否则修改它是没有任何作用的。
Under normal circumstances, a write request is written directly to cache and incurs no delay because physical disk access is not required.
在正常的环境中，一个写请求是直接写入到缓存中而不会引起延迟的，因为它不需要访问物理磁盘。
There is no expiry on a cache manifest, so everything stays cached unless the user clears the cache or the manifest file changes.
缓存清单没有过期一说，因此所有资源都将保持缓存状态，除非用户清空缓存或清单文件更改。
This means that inline cache code no longer use node objects.
也就是说内联缓存将不会在使用节点对象。
This forces the cache to be reloaded from the disk, and thus the cache will be no more than 10 minutes stale.
这将强迫缓存从磁盘重新加载数据，因此缓存数据的过时不会超过10分钟。
It is important to note that file system caching was disabled by specifying the no file system CACHE clause when each table space in the database was created.
重要的是，要注意当每一个数据库表空间创建时，文件系统缓存已经通过指定NOFILESYSTEM cache子句并被禁用。
This would result in a high number of cache invalidations and hence there would be no gain in performance.
这将会导致大量的缓存失效，因此性能不会得到提高。
This would result in a high number of cache invalidations and hence there would be no gain in performance.
