Some configuration details would be nice. What storage engine was used for MySQL, for example? MyISAM only supports table-level locking (and thus one-at-a-time inserts), so I wouldn't be surprised if (assuming MyISAM was used for this test) InnoDB was faster for a test that involves pure concurrent insertion. Otherwise, as others have noted, benching the connection time is unrealistic.
