OBIEE 11.1.1 - How-to enable HTTP compression for IIS 7.0+ HTTP Server

1.  HTTP Compression should be enabled on the OBIEE site level as performance may hindered if enabled globally.

Tip: Run the following command line option to apply Dynamic Compression on OBIEE web site level, note in below command replace the “obiee” website placeholder with your web site name:

Navigate to Path: C:\Windows\System32\Inetsrv\ and Run the command: Appcmd.exe set config "obiee" -section:system.webServer/urlCompression /doDynamicCompression:"True"

2.   Only static compression is installed by default. Ensure dynamic compression feature is installed via Web Server (IIS) > Add Role Services Wizard; for step by step details refer to IIS 7.x documentation. Increase the compression level of static and dynamic files. Note: dynamic compression level default value is 0 and for static compression level default value is 7. As stated below change the level of compression (in gzip) for dynamic files to 7 and for static files to 9

Tip: Run the following command line option to increase GZip Compression Level:

Navigate to Path: C:\Windows\System32\Inetsrv\ and Run the command: Appcmd.exe set config -section:httpCompression -[name='gzip'].staticCompressionLevel:9 -[name='gzip'].dynamicCompressionLevel:7 

Important Note: Raise the dynamic compression level above seven only if you need more network bandwidth and have sufficient CPU capacity to handle the extra load.

3. Restart the IIS HTTP Server.
