    Description

      We currently use java Formatter for audit log formatting. I've done some experiments with it versus simply creating a string of the same format using StringBuilder and apparently if we were to use StringBuilder we can make audit log function 5-10x faster.
      Since it is a useful feature and the namenode under heavy load logs a lot this performance improvement is worth it.
