I see.
In our case, as i had earlier mentioned, each query would be within
its own transaction. When we execute the same query for say 40
times, the number of i/o reads is comparabable to the number of i/o
writes. However, when the loop goes to around 10,000, the number of
i/o writes is very much larger than the number of i/o reads.
Any clue?
