 ## Performance Considerations
-Note that analyzer has very high CPU and memory demands, and often takes a considerable amount of time to complete. Analyses should never be run on live production servers since it can severely degrade the performance of the system.  Use of the file system or registry (on Windows systems) will add significant time to the collection and analysis.
