Optimum settings for Discussion settings of WordPress

Some cache plugin tend to bypass cache over comment_author cookie which expires in 347 days.

  • When this is set, it allow WordPress to serve personalized experience in comment author by auto-filling name, email, site URL but this affect perf. Means returning visitor will have always uncached response.

  • Worst, when this is checked and plugin dont bypass cache over ‘comment_author’ cookie. In that case, visitor’s email visitor@example.com get exposed!

So, must uncheck this option for better performance for returning visitors.
