Rob,
it is not that simple: you were talikng about 5 LPARs talking to each other.
HOW are they "talking" with each other ?
Do you use separate (dedicated) LAN Adpaters, are they sharing one
integrated virtual LAN, how are thes lines defined and so on.
All this makes a difference.
When routing metric has been tuned by a "specialist", then I wouldn't
wonder about ftp going out on one external nic and coming in on the
other, bypassing the existing better internal connection ...
TCPIP buffers should be set to something higher than your 8192,
but 65535 should be enough.
I had a customer with a Virtual IP setup for load sharing and redundancy,
where the consultant chose 576 bytes as  the MTU for that line.
It made a HUGE difference when I changed that to 1496.
Virtual lines should use 8996 as their MTU.

HTH,
Philipp
