      If we have a lower performance for MariaDB 10.0.1 for the same queries
      with the same execution plans we need all possible data to analyze the
      problem. To have the results of a profiling of the underperformed query
      would be perfect.
      Bare in mind only that MariaDB 10.0.1 is based on MySQL 5.6.5. So a
      worse performance of MariaDB 10.0.1 in comparison with MySQL 5.6.5 on a
      query indicates that we have probably a bug in our code.

      Please focus first on simple queries like Q1 and see why the numbers are
      worse there (if they are really worse) than for MySQL 5.6.5.

      Axel,
      Sergey's idea to factor out InnoDB seems to be quite productive.
      Could you please to get the same profiles for the MyISAM DBT3
      as you got for InnoDB DBT3?
