In order to enable compression (herein gzip), there are several steps that have to be completed.

Enable Compression in IIS

• From the IIS snap-in, right-click on the Web Sites node and click on Properties
• Select the Service tab - Enable Compress application files
• Enable Compress static files
• Change Temporary Directory to the folder that you created above, or leave it at it's default
• Set the max size of the temp folder to something that the hard drive can handle. e.g. 1000.
• Save and close the Web Site Properties dialog

Note: The temporary compress directory is only used for static pages. Dynamic pages aren't saved to disk and are recreated every time so there is some CPU overhead used on every page request for dynamic content.
