unfortunatly you left out the total hosts line ;-)

do you have anything else on the scsi chain?  The slowest device will
(I understand) drag all the other ones down with it.  SO if you (like
me)
have an old scsi1 cdrom drive that only talks the slowest protocol
you'll
get stuck down at what, 10MB/sec?  Those who know for sure feel free
to
correct me if I'm 'worng' (sic)

(And I'm surprised, because the same kind of tests that I've run on my
scsi
systems always show scsi better than IDE...  Especially since you've
shown
that there are apparently no bandwidth bottlenecks after the ide or
scsi...
hey, wait.  What kind of card are these?  8-bit, 16-bit, PCI, ??? If
the
hardware interface between the controller and the memory is different
between the two types of controller you can see important effects
there.)
