--   MySQL note ( http://dev.mysql.com/doc/mysql/en/storage-engines.html ):
--     ENGINE is the preferred term, but cannot be used before MySQL 4.0.18.
--     TYPE is available beginning with MySQL 3.23.0, the first version of
--     MySQL for which multiple storage engines were available. If you omit
--     the ENGINE or TYPE option, the default storage engine is used.
--     By default this is MyISAM.
--
--  Please create additional indexes on keys when needed, or drop suggested
--  ones as appropriate to optimize queries needed by a management application.
--  See your database documentation for further optimization hints. With MySQL
--  see Chapter 15 of the reference manual. For example the chapter 15.17 says:
--  InnoDB does not keep an internal count of rows in a table. To process a
--  SELECT COUNT(*) FROM T statement, InnoDB must scan an index of the table,
--  which takes some time if the index is not entirely in the buffer pool.
--
--        Wayne Smith adds: When using MySQL with InnoDB one might want to
--  increase buffer size for both pool and log, and might also want
--  to change flush settings for a little better performance. Example:
--    innodb_buffer_pool_size = 384M
--    innodb_log_buffer_size = 8M
--    innodb_flush_log_at_trx_commit = 0
--  The big performance increase is the first two, the third just helps with
--  lowering disk activity. Consider also adjusting the key_buffer_size.
