要追踪到您的应用程序在速度上的确切限制，您需要准备处理困难和简单的性能问题。
To track down the true limits on your applications' speed, you need to be prepared to tackle both the hard and the easy problems of performance.
如果可以，应该避免使用该选项，因为它可能产生性能影响并降低应用程序的速度。
If possible, you should avoid using this option because it can have a performance impact and reduce application speed.
堆大小的这些上下浮动可能会降低应用程序的速度，但如果同一系统上运行的其他程序不需要物理内存，则没有必要这样。
These fluctuations in the heap size can slow down the application and are unnecessary if the physical memory is not needed for anything else running on the same system.
这将有助于提高应用程序的速度并增加XML文档的灵活性。
This should help speed your applications and increase the flexibility of your XML documents.
我们可以做优化，但应用程序的速度将会变慢至少一个数量级，内存的使用也会扶摇直上，因为有这么多的类被创建。
We could optimize, but the application would be at least an order of magnitude slower. Memory use would also skyrocket, as so many classes are created.
这就是嵌入式脚本编写的威力：既获得已编译应用程序的速度，又具有动态脚本的可扩展性。
That's the power of embedded scripting: you take the speed of compiled applications and provide the extensible power of dynamic scripting.
这个折衷允许框架大幅度加快应用程序开发的速度。
This tradeoff allows the framework to drastically speed up application development.
构建和部署应用程序的速度如何？
不幸的是，错误和糟糕的编码实践不仅不太专业，而且可能减缓应用程序的速度。
Unfortunately, errors and bad coding practices are not only unprofessional but can also slow down your application.
很多人都知道，配置不佳的GC会使用大量资源，而且还会降低应用程序的速度。
Most people know that poorly configured GC can use a lot of resources and slow an application down.
显然，大量的垃圾收集可以真正减慢应用程序的运行速度。
Obviously, a lot of garbage collection can really slow down your application.
优化软件用于修改和压缩系统，这样应用程序执行速度更快或操作更少的内存存储量和其他资源。
Optimized software is used to modify and compress a system so that an application can execute more rapidly or operate with a reduced amount of memory storage and other resources.
这意味着如果XML文档中的名称空间声明比较多，就会有大量额外的回调从而降低应用程序的速度。
This means that if your XML documents include a relatively large number of namespace declarations, you get lots of additional callbacks and it slows down your application.
但反过来也正确：明智地选择垃圾收集参数实际上会使应用程序运行速度更快。
However, the opposite is also true: a wise choice of garbage collection parameters can actually make an application run more quickly.
但是事务的开销也很大；它们会消耗宝贵的资源并且会减慢应用程序的速度。
