For our application, a 1.6 GHz Pentium M Notebook currently
hold the top of the benchmark, slightly outperforming
dual 2.4 Xeon Systems with RAID arrays.
This is with 8i, but im my experience, the performance
characteristics of 9i are the same.

And no, I can't explain those results - with a single
60 GB IDE disk, the Notebook should be much slower.
(It's even faster with an external 200MB USB2 drive, btw.)

I'd agree, especially for DBMS workloads.

If system, especially IO, performance does not play a
large role in your application, the results above probably
don't apply. Our benchmark is rather write-intensive.
