Re: Tim Gorman's "...Cost-Based Optimizer.doc"

I was told IBM's ESS (Shark) is capable of that too. Not sure if it 
really does.
It doesn't actually  require much "intelligence" (I'd say even less than 
Geraldo) to pre-fetch the next stripe size whenever full stripe size 
chunk requests are received.
Whether that is "smart" is a different question.
