The following quote[1] from Frank Soltis seems to agree.

...", but the RS/6000 was just an AS/400 without the I/O processors as
UNIX cannot make use of the capabilities of I/O processors. Thatÿs why
the AS/400 would always win over the RS/6000 for I/O intensive
applications whilst the RS/6000 is the machine for compute intensive
scenarios."

[1] http://www.it-director.com/article.php?id=2416 I found this linked
to from one of the Linux news sites I read. With the advent of Linux on
iSeries, the iSeries seems to be getting mentioned in the Linux press
much more often. No bad thing for either platform (IMHO).
