网站速度优化模块HttpCompressionModule

为了优化网站的访问速度，准备采用 HttpCompressionModule 6 对传输数据进行压缩，下载了 HttpCompressionModule 6 , 并按照示例程序中的 web.config 配置了网站的 web.config 。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
   <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
   <sectionGroup name="blowery.web">
         <section name="httpCompress" type="blowery.Web.HttpCompress.SectionHandler, blowery.Web.HttpCompress"/>

    <!--
   Here's an example on how to change the algorithm or compression level
   
      <compressionModule preferredAlgorithm="deflate|gzip" compressionLevel="high|normal|low"/>
   
   so, to use deflate by default, and high compression, you would use the following line
   -->
    <httpCompress preferredAlgorithm="gzip" compressionLevel="high">

使用效果：
使用 HttpCompressionModule 自带的 Fetch 工具进行测试，测试结果如下：

测试结果说明 :
第一行数据是未使用 HttpCompressionModule 的测试结果。
第二行数据是使用 deflate 压缩算法进行压缩后的测试结果。
第二列数据是 Web 服务器传递到浏览器的文件大小。很明显，压缩后传输数据大大减少，有效地节约了带宽。
TTFB ―首字节平均响应时间（ Gets the number of milliseconds that have passed before the first byte of the response was received. ）
TTLB ―末字节平均响应时间（ Gets the number of milliseconds that passed before the last byte of the response was received. ）
Transit ―传输数据到浏览器的时间。
从测试结果可以看出 , 采用 HttpCompressionModule 后访问速度有明显改善。
