Sets the mutex alignment, in bytes. It is sometimes advantageous to align mutexes on specific byte boundaries in order to minimize cache line collisions. This parameter specifies an alignment for mutexes allocated by Berkeley DB.
         The syntax of this parameter in the DB_CONFIG file is a single
         line with the string mutex_set_align, one or
         more whitespace characters, and the mutex alignment in bytes.
         Because the DB_CONFIG file is read when the database environment
         is opened, it will silently overrule configuration done before
         that time.
