I'm not sure I explained my question properly, let me try it this way.

Let's compare two systems that generate 3gb/hr.

One has 3 - 100mb redo logs and the other has 3 - 1gb redo logs.

If the transactions were evenly distriubted over time, the first system would generate a log file every 2 minutes. The other every 20 minutes.

What's the rationale for sand-bagging I/O? Would it be better to more evenly distribute it over time?

Just curious,

Ken
