The obiee tuning guide available here https://blogs.oracle.com/proactivesupportEPM/entry/wp_obiee_tuning_guide lists a number of checks for optimization.
The script attached here https://blogs.oracle.com/pa/resource/CheckObieeTuningGuidev4_01-2014.zip automates these checks. It is only reading from the obiee server and it will not modify any values. The script outputs the current values, that you can compare with the recommended ones.
