I've migrated a datawarehouse to my new exa and now ran io_calibrate on it. To
my horror it returns worse figures than i expect, eg 500mb per second
throughput. The old & tired ODA clocks in at 3 times that, and more.. We do see
good performance on real queries, so the calibration is cearly wrong..
Any one has any pointers? Should I use auto-dop at all on an exadata?
