I need a response that includes an explanation of the benefits of using a content management system (CMS) for a business. Your response should contain at least 5 sentences and no more than 10 sentences. Highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. Include the keyword *efficiency* in the response. At the end of your response, please explicitly add a postscript starting with *P.S.*.
