总结：
EXPDP/IPMDP仅仅能在server上执行，其执行效率全然取决于磁盘I/O，而EXP/IMP不仅能够执行在server上。也能够执行在client上。所以除了磁盘I/O的制约因素，还有网络方面的因素。
EXPDP/IMPDP比EXP/IMP性能有非常大的提高，当中影响最大的就是paralle。通常设置为CPU的个数。通过该參数能够并行导出，大大提高导出速度。而EXP/IMP是没有这个功能的，最多也就仅仅有一个DIRECT=Y,使导出不用经过SELECT到SGA的BUFFER中。提高的速度是有限的，注意他们之间的语法也有不小的差别，參数不可互相替代。
EXPDP/IMPDP能够通过remap_schema和remap_tablespace直接实现不同用户和表空间之间的数据迁移;而EXP/IMP则略微麻烦一点，须要ALTER TABLE xxx MOVE TABLESPACE xxx/ALTER INDEX xxx REBUILD TABLESPACE xxx方式来实现。move相当于把表再重建一次，能够改动storage參数(如initial、pctfree、pctincrease等)。还能够move到另外的表空间，假设不指定表空间。则在原来的表空间中move，因此做move操作时，目标表空间须要保证有这个表相同大小的剩余空间，整个操作相当于exp/imp(从表空间A导出到表空间B)。move完表后要重建索引。
基于以上几种原因。如今做数据逻辑迁移都是用EXPDP/IMPDP而非常少再使用EXP/IMP了。
