Mirroring on 10.10

We have just taken delivery of a 5 processor T520, running HP-UX
10.10. The system is set up such that we have a 4 gig system disc on
its own F/W controller, and 14 x 2 gig discs mirrored over 4 extra F/W
controllers. This is being used mainly to access an Oracle 7.2.3
database.
Initial results indicate much less of a performance increase from the
single processor D350 that is used for development. This machine is
set up to use asynchronous IO and the kernel is configured as
recommended by HP and Oracle.
Using glance, the machine seems to have no bottlenecks anywhere, is
just doesn't seem to be running at its full potential. I suspect that
it is the disc mirroring that is the problem. Do I need to rejig the
kernel for that as well?
Any suggestions will be extremely gratefully received... explaining to
out customer just why they need this machine when it doesn't work to
its full potential could be very embarassing!
TIA
