性能优化英语

搜一下：性能优化的数据中心，英文简称是“POD”么？

Completing the work of designing, assemblying, testing, and optimizing the structure and performance of the first batch of products.

My computer run slowly.最简单的说法

最表现出的压缩你的Apache服务器可以使差异如何网站功能，它使的印象。 Even fractions of a second matter, especially on dynamic sites.即使分数第二个问题，尤其是在动态网站。 This article looks primarily at configuration and installation, two areas where you have the most control.这篇文章看起来主要是在配置和安装，你有两个领域最控制。 Measuring and Improving Performance测量和提高性能Apache was designed to be as fast as possible.阿帕奇被设计成尽可能快。 It's easy, with a fairly low-powered machine, to completely saturate a low-end Internet link with little effort.这很容易，具有相当低功率机，完全饱和，几乎努力低端互联网链接。 However, as sites become more complex and the bandwidth needs of different connection types increase, getting the best performance out of an Apache installation and Web sites becomes more important.然而，由于土地变得更加复杂，带宽需求不同的连接类型的增加，获得最佳的性能是Apache的安装和网站出来就变得更加重要。 Enhancing performance means nothing if the changes achieved are only minor gains.提高性能的变化意味着什么，如果只是轻微取得收益。 Spending hours or even days finely tuning a server for just a few percentage points is a waste of time.花费数小时甚至数天精细微调只是几个百分点的服务器是浪费时间。 The first step, therefore, is to determine how fast the server is running and its general performance level so you can work out how to improve performance and measure the changes.第一步，因此，是确定如何快速的服务器正在运行，并且其综合性能水平，以便您可以解决如何提高性能和测量的变化。This is not the first time we've discussed Apache testing (see Staying Out of Deep Water: Performance Testing Using HTTPD-Test's Flood).这不是我们第一次讨论了Apache的测试（见在外面深层水：用httpd性能测试试验的洪水）。 As was noted previously, determining which parts of your Web application are causing the problem — particularly identifying whether it's Apache or the application environment you are using with dynamic sites — can be difficult.正如前面指出，确定哪部分是您的Web应用程序导致了问题 - 特别是究竟是它的阿帕奇或应用程序环境你用动态网站的使用 - 可以是困难的。 Identifying problems in dynamic applications is beyond the scope of this article, but we will look at ways to generally improve the speed of Apache and how it interacts with other components to support a Web site.在动态应用识别的问题已经超出了本文的范围，但我们会研究如何把Apache的普遍提高速度以及它如何与其他成分相互作用，以支持网站。 Host Environment主机环境Regardless of operating system, the following optimization principles apply:无论操作系统，下面的优化原则适用于：• Keep other background applications to a minimum. •将其他后台应用到最低限度。 If you are really serious about performance, this should even include some background processes that some would consider vital.如果你真的表现严重，本应甚至包括一些后台进程会被人认为是至关重要的。 For example, in Unix, switch off NFS, any printing services, and even sendmail if it's not needed.例如，在Unix上，关掉NFS的，任何印刷服务，甚至sendmail的，如果是没有必要的。 Under Windows, use the System control panel to optimize the system for applications and system cache, and optimize the system for performance.在Windows下，使用系统控制面板来优化应用程序和系统缓存系统，优化系统性能。 Make sure, of course, any required applications or services, like MySQL are still running.确保当然，任何所需的应用程序或服务，如MySQL仍在运行。 • Avoid using the system.If you start compiling applications, editing files, or otherwise employing the machine, you'll reduce its Web serving performance. •避免使用system.If你开始编译应用程序，编辑文件，或者以其他方式雇用的机器，你会减少它的Web服务的性能。 If you must edit components or install software, build or edit the components on another machine and copy them over.如果您必须编辑组件或安装软件，建立或编辑另一台计算机上的组件和复制他们。 • Keep your system up to date. •您的系统保持最新状态。 Although a good idea just from a security point of view, software patches and updates can make significant improvements to network and I/O performance.虽然只是从安全角度来看，软件补丁和更新好主意，可以显着改善网络和I / O性能。

以上用slow或者fast的都没错, 如果你想像中文一样说电脑"卡", 应该用lagging, a lagging pc
