Hi All,

The question may be wispy.
We have 14 CPU sun box,8i 2 node OPS. Not under heavy load.

In our case it is taking 21.86 sec for 6126 blocks (from disk)

db file sequential read                      6126        0.29         21.86

Approximately how long it should take to read 6000 blocks?

call count cpu elapsed disk query current rows
