Let's see. What was that rule of thumb I heard from Kevin Loney? I think it
was that each index slows down DML by a factor of 3 (at least for batch jobs
where you have to worry about recursive SQL). So 23 indexes would run about
70 times slower than no indexes. Do I sense a hardware throwing contest??
