Hi,
It just occurred to me that it is not necessarily the case that reading the indexes causes a lot of random I/O (on the index itself).
I mean, maybe the index is generally read sequentially and then, when retrieving the data, there is a lot of random I/O. (which could be on a different spindle..)
Can anyone tell me or point me to some info?
thx,
WBL
