RE: Index move"having the index on a different disk from the table should give you better performance."

Why ?

Seema,

The big question: where is the table? Forgetting about RAID, having the index on a different disk from the table should give you better performance.

As far as moving the index to another tablespace without considering the table, it depends on what else that disk is doing. If it is hardly used, then you might get a performance increase. If the disk is busy, moving an index to it could slow things down even more.

Hi
Is any performance gain/impact if I move unique indexes from one tablespace to another tablespace if both tablespaces are on diffrent physical disk?

Thanks
