[B]Have you set up your table with an initial space enough to contain new records, Oracle will use more time to allocate new extents if the table does not have enough space. Are the T_1 and T_2 table have simular index structure ? Index is another overhead to insert statement. [/B]
做测试时,我们曾经碰到过类似问题,后来把表的存储参数加大到2M.
速度慢的问题得到很大的改善. |
