Has anyone else notice that these two can be somewhat different? In a high transaction system, I typiucal try to reduce LIOs when I write queries.

For last 6-8 months, Ive been doing alot of ETL and nightly batch data loads. Ive found that there are times when I can improve response time by 20-30%(which can be significant in a batch process) and at the same time increasing LIOs by the same amount. Ive found this to be the case with large index fast full scans. Unfortunately, I forgot to save the test cases. Im not concerned about scaling up users here.

Has anyone else noticed this?
