Comparisons between systems *are not meaningful*. That's why the
numbers I gave were about *my* system under varying circumstances.
(Hell, comparisons between a system at 5AM and the same system at
5PM aren't even meaningful!)

Now, with your machine, you're getting, you claim, 12,000
articles/hour == 3.33 articles/second -- you could get that with
disks that are 67% faster than mine (not at all impossible, mine
aren't especially fast) or shorter retention periods on your
newsgroups (the speed of your innd can depend quadratically on
this and I keep mine around for a long time -- 25 days on the
popular groups). And there are any number of other things that
can contribute one way or another to the processing speed.
