How to enable compression on IIS 7 in windows 7 using web.config

Question

I am using page speed tool in google chrome and find below results.

For Localhost website: Page Speed Score: 92/100

For website IIS 7: Page Speed Score: 61/100

I used below code in web.config to enable compression

 <system.webServer>
    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
      <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
      <dynamicTypes>
        <add mimeType="text/*" enabled="true"/>
        <add mimeType="message/*" enabled="true"/>
        <add mimeType="application/javascript" enabled="true"/>
        <add mimeType="*/*" enabled="false"/>
      </dynamicTypes>
      <staticTypes>
        <add mimeType="text/*" enabled="true"/>
        <add mimeType="message/*" enabled="true"/>
        <add mimeType="application/javascript" enabled="true"/>
        <add mimeType="*/*" enabled="false"/>
      </staticTypes>
    </httpCompression>
    <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0"/>
      <remove name="OPTIONSVerbHandler"/>
      <remove name="TRACEVerbHandler"/>
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0"/>
    </handlers>
    <modules runAllManagedModulesForAllRequests="true" />
  </system.webServer>

But still score on IIS are 61/100 and its showing ENABLE COMPRESSION .

What am I missing in my config to enable compression ?

Answer 1

This is what I added to my web.config when page speed tool reported low score due to no compression.

<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
  <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
  <dynamicTypes>
    <add mimeType="text/*" enabled="true" />
    <add mimeType="text/javascript" enabled="true" />
    <add mimeType="text/css" enabled="true" />
    <add mimeType="message/*" enabled="true" />
    <add mimeType="application/x-javascript" enabled="true" />
    <add mimeType="application/javascript" enabled="true" />
    <add mimeType="*/*" enabled="false" />
  </dynamicTypes>
  <staticTypes>
    <add mimeType="text/*" enabled="true" />
    <add mimeType="text/javascript" enabled="true" />
    <add mimeType="text/css" enabled="true" />
    <add mimeType="message/*" enabled="true" />
    <add mimeType="application/javascript" enabled="true" />
    <add mimeType="application/x-javascript" enabled="true" />
    <add mimeType="application/atom+xml" enabled="true" />
    <add mimeType="application/xaml+xml" enabled="true" />
    <add mimeType="image/png" enabled="true"/>
    <add mimeType="image/jpg" enabled="true"/>
    <add mimeType="*/*" enabled="false" />
  </staticTypes>
</httpCompression>
<urlCompression doDynamicCompression="true" doStaticCompression="true" />
