Well, for performance, all bets are off for the dev Windows port. Last I
checked, the Win32 team was still working on *stability* and hadn't yet even
looked at performance. Not that you can't improve the query, just that it
might not fix the problem.
Therefore ... your detailed feedback is appreciated, especially if you can
compare stuff to the same database running on a Linux, Unix, or BSD machine.
