Do different tablespaces make a performance difference?

I had thought that--barring security reasons--splitting schemas into their own tablespace was mostly pointless in recent Oracle versions. In other words, pretend you have an instance with:

schema1 -> tablespaceX -> datafileX (on "D" drive)schema2 -> tablespaceX -> datafileX (on "D" drive)schema3 -> tablespaceX -> datafileX (on "D" drive)

and you have another instance with:

schema1 -> tablespace1 -> datafile1 (on "D" drive)schema2 -> tablespace2 -> datafile2 (on "D" drive)schema3 -> tablespace3 -> datafile3 (on "D" drive)

Assuming that each schema had the same amount of usage, I had thought that there was no difference in performance between the two systems. Performance is roughly the same, even if you have different drives

Howdy, Stranger!
