no no no. I see it -- it is Oracle Sales math. See that 1.9 and that 1.45?
Well -- the ones match so just drop them. Then .45 is twice as fast as .9,
so obviously your test confirms their results. Oracle Sales math has the
interesting feature that any set of experimental results can be misused to
support the desired claim. But I really thought the use of Oracle Sales math
was currently in disfavor at Oracle.

Seriously, though, I'm wondering what tests they ran before making such a
claim. I'll try to remember to ask at our meeting in August.

Hello Jared,

I believe you must double your input voltage in order to get
that 2x improvement in PL/SQL execution time. Do you have a
240-volt outlet handy?

(Just kidding Jared! Please don't try that at home!)
