例如，客户对象映射并不是性能测试模型的关键构件。
To access some information in SAX, you need to cast an object to a different interface; this carries a performance cost.
要访问SAX中的一些信息，必须将对象强制转化成不同的接口，这样就带来了性能上的开销。
However, there could be a price to pay in terms of performance. There is (potential) overhead in object creation and in method dispatch.
但是，这可能会以牺牲性能为代价，对象创建和方法分配都可能会存在开销。
Regardless of the technique you use for the implementation code, repeatedly updating a single object can cause a performance hotspot in the repository if the volume is high.
不管您使用什么技术来实现代码，重复地更新一个对象会导致高访问率储存库的性能下降。
The first level consists of the performance object, which is a unit that can model a physical device or abstract component in a system.
第一级包括性能对象，它是可以为物理设备建模，或者抽象系统中组件的单元。
In addition to being important for performance, object alignment may be required for particular devices or hardware configurations.
除了对于性能很重要之外，某些设备或硬件配置也需要对象对齐。
Similarly the application design can be tuned for performance: Fewer object creations, ongoing database refinements, and using database connection pooling.
同样地，应用程序设计也能调优性能：更少的对象创建、实时的数据库优化以及使用数据库连接池。
Repeatedly creating and throwing out objects carries very little performance overhead, but holding onto existing object instances for reuse creates significant work for the garbage collector.
重复创建并丢弃对象的方法产生很小的性能开销，而持有现有对象实例以便重用的方法则为垃圾收集器增加大量的工作负担。
When an object needing to be advised is invoked very many times and no proxy performance overhead is acceptable.
当一个对象需要被通知会被多次调用，而且不接受任何代理性能负载。
The settings of the various object properties have a significant impact on the behavior and performance of the JMS application.
各种对象属性的设置对JMS应用程序的行为和性能有重要影响。
Run time: performance degradation (even when using object pools), both in response time and CPU consumption, is evident with complex nested objects.
运行时：在响应时间和CPU的消耗两者上性能的下降(即使当使用对象池时)，明显有着复杂嵌套对象。
The second level consists of the performance counter, which is an attribute of the performance object.
第二级包括性能计数器，它是性能对象的属性。
Lecturers object to new rules that impose regular performance evaluations and give more powers to university presidents to manage, promote and pay staff.
讲师们反对实施新准则——新准则拟执行定期业绩评估，并给予校长更多关于管理、提升和薪酬方面的权限。
They asked participants to complete more maths tests—and also tests in which they mentally rotated an object—while investigators chided them about their performance.
在实验中，他们要求试验者做更多的数学题（这些题还是会引起试验者们的心理起伏），同时，研究者们还是会对试验者们的表现指指点点。
This means that you only pay the performance penalty of building an object model for those portions of an XML document which actually need to be accessed through the model.
这意味着，只有为实际需要通过模型访问的XML文档部分构建对象模型才会带来性能损失。
Both the creation of the factory and the manager object incur high performance costs (similar to connecting to a database with JDBC).
工厂的创建和管理器的创建都会导致较高的性能代价(类似于用JDBC连接到一个数据库)。
Any problems discovered in the alternate JPA provider (such as object mappings, database interaction, performance concerns, and so on) will need to addressed with that provider.
在替代jpa提供者中发现的任何问题(比如对象映射、数据库交互、性能问题等)都需要与该提供者一起解决。
I typically add the following counters with Process selected as the Performance object.
我一般会添加如下计数器，选中process作为Performance对象。
This article discusses two potential areas that can provide powerful extension points for Rational Performance Tester: object extension via a super class, and reusable utilities via static methods.
本文讨论了两个潜在的区域，该区域为RationalPerformance Tester提供了强大的扩展点：通过一个超类来进行对象扩展，以及通过静态的方法来使用可再用设施。
We used the Memory Object, Pages per Second Counter, to measure performance.
我们使用内存对象PagesperSecond Counter来衡量性能。
By selecting the process performance object in the "Add counters" dialog, a comprehensive list of process level counters are displayed (Figure 5).
