Hi all I was reading the High Performance MySQL book (by O'Reilly) and there was mentioned that executing a count(*) is slower on the InnoDB engine compared to the MyISAM engine, because InnoDB tables do not keep track of the number of the records. I just wanted to know that if this performance degradation is a feature of all transactional engines (i.e. Oracle, DB2, PostgreSQL, ...) or it's just a weakness of the InnoDB engines?
