批量插入，事务插入或两者？哪个更快？

Question

哪个更快？

1. 批量插入

   insert into table values (1,2), (3,4), (5,6),...  ;
   

2. 交易记录

   begin transaction;
    insert into table values (1,2);
    insert into table values (3,4);
    ...
   end transaction;
   

3. 两个

   begin transaction;
    insert into table values (1,2), (3,4), (5,6),...  ;
   end transaction;
   

是1还是2等效？
