对于整个日志来说，GC开销(即花费在执行GC上的时间)大约为5%，这是非常不错的。
A large chunk of binary data takes up less space than its encoded representation, so MTOM can reduce transmission time (although it incurs some processing overhead).

One word of caution about all of these time-measurement APIs: they have execution overhead, which affects how frequently they can be called before they overly distort the measurement.

Sometimes it meant dropping a feature because it was just too expensive, or because it wasn't important to enough users to justify the overhead at run time or to the codebase.
有时候会因为功能开销过大，或者因为不够重要而让用户投入运行时开销或加入代码库。

使用OpenGL，可以实时地呈现高品质的3d场景，而没有光线跟踪器那样大的开销。
It looks like the tracer adapter could also use some tuning, but the hard reality is that all instrumentation imposes some level of overhead. Figure 11 displays the elapsed time results for this test.
跟踪适配器看起来好像也能使用一些调优，但事实是所有的插装都会导致某种程度的开销。
To minimize "object model impedance" (the run time and maintenance overhead of translating between object models), applications should internalize the vendor service information model.
为了尽可能减小“对象模型阻抗”(对象模型间转换的运行时与维护开销)，应用程序应该将供应商服务信息模型内部化。
Fresh lava is bright red, an indication that it was active at the time the satellite flew overhead.
起初的熔岩是亮红色的，迹象表明在卫星从上面飞过的时候这个火山是活的，一层一层的不断翻滚的沙尘暴从过热的裂缝中升起，火山喷发成了一道风景线。
By using the scripts in this article, you can eliminate much of the hardship while reducing the time overhead that might normally be associated with the process.
通过使用本文中的脚本，可以减少许多困难，同时减少通常可能与这个过程有关的时间花费。
This process rigor is often part of the project's lifecycle whether it adds value or is just overhead that burns time and budget.
这一处理过程的严格性通常是项目开发周期的一部分，无论它是添加值还是烧钱和时间。
They are proven to produce the low-error estimate and incur almost no run-time overhead.
它们被证明可以产生低误差的估计，并且几乎不占用运行时开销。
However, having to perform a separate activity to publish your work, after having spent time developing it, is an overhead that people don't naturally want to accommodate.
然而，由于每个人是分别执行活动来发布自己的工作，所以在花费时间开发之后，还存在其他人不那么自愿进行调整的问题。
Make use of overhead cabinets for folders and files you need but don't use all the time.
充分利用头上的柜子来装那些你需要但是并不常用的文件夹和文件。
Saving time lowers the administration overhead, especially when spread across many servers or desktop computers.

By making data types consistent within the DDL, there is less overhead associated with conversion of data at query run time.
通过在DDL中确保数据类型一致，在查询运行当中与数据转换相关的开销会比较小。
To reduce management overhead, we need to delete unused and irrelevant files from time to time.
为了降低管理负担，我们需要不时地删除无用和不相关的文件。
Obviously, if each unit of work were two, or ten, or one hundred times as large as a single string method call, then the proportion of time spent in thread overhead would be correspondingly small.
显然，如果每个工作单元都相当于单个字符串方法调用的两倍、十倍或一百倍，那么所花费的线程开销比例就相应地更小了。
Since the WSDL rarely changes, many developers embed the WSDL definition into their code to avoid the overhead of getting the WSDL every time.
