RE: Veritas Quick I/0 and Oracle/ Asycnchronous I/O

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??
