One of the most important aspects of owning a website is having it rank well with search engines.

拥有网站最重要的方面之一就是让它在搜索引擎中排名很高。

After all, no one creates a site intending for it to be buried on page 20 of a Google search.

毕竟，没有人创建一个打算将其埋在Google搜索第20页上的网站。

CodeDragon SmartCache was designed as a powerful performance and caching system for WordPress websites yet easy enough for the non-technical site owner to understand.

CodeDragon SmartCache是​​为WordPress网站设计的功能强大的性能和缓存系统，但对于非技术性网站所有者而言，它足够容易理解。

Employing several “layered” capabilities such as minifying, combining, page and browser caching and CDN support, SmartCache is able to:

通过利用多种“分层”功能，例如最小化，组合，页面和浏览器缓存以及CDN支持，SmartCache能够：

1. Condense served resources to improve network bandwidth
2. 压缩服务资源以改善网络带宽

3. Improve user experience by reducing the time it takes to offer your site content
4. 通过减少提供网站内容所需的时间来改善用户体验

5. Focus on the key aspects that search indexing sites like Google regard when ranking the site
6. 重点关注像Google这样的搜索索引网站在对网站进行排名时所考虑的关键方面

After installing SmartCache it will automatically activate the most optimal settings for your site.

安装SmartCache后，它将自动为您的站点激活最佳设置。

If you would like to further customize these settings, this introduction will walk you through some of the key steps.

如果您想进一步自定义这些设置，本简介将引导您完成一些关键步骤。

A more detailed instruction is available in our Startup Document.

我们的启动文档中提供了更详细的说明。

Ultimately, we have built SmartCache so that getting up and running does not require making manual changes to the wp-config.php, .htaccess, or other site files.

最终，我们构建了SmartCache，因此启动和运行不需要手动更改wp-config.php，.htaccess或其他站点文件。

Minifying

缩小

At the lowest level, SmartCache will minify Javascript, CSS stylesheets, fonts, and HTML content.

在最低级别，SmartCache将最小化Javascript，CSS样式表，字体和HTML内容。

As well, it can automatically minimizes render-blocking files, and remove query strings.

同样，它可以自动最小化渲染阻止文件，并删除查询字符串。

Combining

合并

By combining files, SmartCache helps to reduce the number of requests for files from the server, thus shortening the amount of time required to load a page.

通过组合文件，SmartCache有助于减少来自服务器的文件请求数量，从而缩短了加载页面所需的时间。

Page Caching

页面缓存

Page caching goes further by implementing GZip Compression, preparing a separate HTTPS cache and serving a “flattened” HTML version of your site’s pages.

页面缓存通过实现GZip压缩，准备单独的HTTPS缓存并提供站点页面的“扁平化” HTML版本来进一步发展。

With GZIp Compression and static HTML content pages are provided with less processing from the server.

使用GZIp压缩和静态HTML内容页面时，服务器进行的处理较少。

Browser Caching

浏览器缓存

At this point SmartCache instructs your server with the preferred expiry periods for several file types, so client browsers can comfortably reuse cached files until they expire.

此时，SmartCache会为您的服务器指示几种文件类型的首选有效期限，以便客户端浏览器可以轻松地重用已缓存的文件，直到它们过期为止。
