    Description

      Data comes from Sandy Bridge system running sysbench OLTP RO in 1 thread against 1 table.

      Call graphs:

      -   0.07%  mysqld  mysqld
         - handler::rebind_psi()
            + 73.91% open_tables(THD*, DDL_options_st const&, TABLE_LIST**, unsigned int*, unsigned int, Prelocking_strategy*)
            + 26.09% open_table(THD*, TABLE_LIST*, Open_table_context*)

      Most time spent for function call convention. It also adds ~0.03% to open_table(). Try to make it inline.
