So do you wish to compare the most expensive AS/400 you can buy to a
486/33.  Give me a break, or better yet give me some compile, & sort
times for say 1000 line RPG programs and 50-100MB database files using
the native compiler and #GSORT.  Even better yet I can mail you the one
I used & We'll compare

So was the SCO Unix on a 486/33 I tested it against.  The SCO box also
had *MORE* Crap hung off it.

Yep, Transactions test the disk & I/O more than the CPU.  I shant argue
with you there.  However, I did the comparison *AFTER* We were switched
over when absolutely NOTHING was going on on the AS/400.  There were
only 3 Terminals and 1 Printer Varied on at the time.  Only one Terminal
was active.  On the '33 at the same time there were 2 Highspeed modems
doing a file transfer, and 3 or 4 people doing Word Processing.  Nothing
Heavy there either.

So does my 486/33 (which was upped to a 66 last month or so).  I've got
a Digiboard C/X system with 4 286 CPU's in it (You know, the stuff your
brothers hang on the RS/6000).  The new ones use a RISC I think.  The
Disk Controller has a 16Mhz 68000 Chip.  And all the Drives Are SCSI (Oh
yea, that needs cpu's huh).  That's 5 more.  Oh and of course the SCSI
tape (8mm) has one too.  That makes a total of 11 dedicated cheap off
the shelf I/O processors, and you ain't just whistling dixie about
offloading.  I did a simple loop test on the Digiboard vs a pair of
16550's on the bus (ISA SIO card), and the System load difference is
amazing.  Like 1/10th.  The SCSI card takes care of the mirroring
transparently too.
