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。
PHP 5 introduces improvements to the object model; also, the underlying memory management has been redesigned with multi-threading and performance in mind.
PHP5改进了对象模型，底层的内存管理也从多线程和性能的角度重新作了设计。
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。

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。
