在某些情况下，例如在性能是应用程序的主要考虑因素的地方，就可能不是最佳选项。
The XML-encoded output of test results was also a handy feature for post-test analysis, as this option captured the embedded performance statistics in the IFX-encoded reply messages.
测试结果的XML编码输出对于测试后分析是一个方便的特性，因为该选项捕获了包含在IFX编码的应答消息中的性能统计。
Although the option enables soft real-time performance and even under load makes the operating system execute more smoothly, it does so at a cost.
虽然此选项实现了软实时性能并且即使在负载条件下也可使操作系统顺利地运行，但这样做也付出了代价。

This option improves performance by enabling you to temporarily leave completed process instances in the database, and then delete them at a later time when the system is less busy.
此选项使您能够将已完成的流程实例暂时保留在数据库中，然后在以后系统不太慢的时候再删除它们，从而改进了性能。
Since the enhanced MDC INSERT performance feature is implemented by specifying it as an option on a table's LOCKSIZE parameter, this means that it can be enabled on a per table basis.
由于增强的MDCINSERT性能特性是通过指定它作为一个表的LOCKSIZE参数上的一个选项来实现的，这意味着它可以在每个表上启用。
The automatic cache-to-file storage option can result in performance issues because it does not have native support for filtering and sorting.
自动缓存到文件选项可能会造成性能问题，因为它本身不支持筛选和排序。
GAE offers an option for developers to pay and keep the inactive JVM in memory for more-consistent performance.
为了获得更一致的性能，GAE为开发人员提供付费的选择让无效的jvm保存在内存中。
The more specific JIT optimization, that was narrowed down to, the less adverse performance effect disabling of this optimization option will have as a workaround.
JIT的优化选项越具体(这可以缩小范围)，禁用这种优化选项产生的性能影响就越小，这样就可能会很容易得到一个解决方案。
That cost is slightly lower throughput and a small reduction in kernel performance because of the added overhead of the CONFIG_PREEMPT option.
代价就是略微减低了吞吐量以及内核性能，原因是CONFIG_PREEMPT选项增加了开销。
The performance trace formatter is a parsing option that formats a dump file containing performance counter data into readable text (see Listing 6).
