We have the SMP installed.  To give it a benefit of doubt, we re-installed
the RS506a.  Also, the second NIC was phyically removed.  Unfortuantely,
there was still no apparent improvement.

Finally, we talked to HP and have the UNIX support team told us to disable
the AMI Raid Monitor (under /etc/idrc.d/amird).  The system started to speed
up.  They said there had been known performance issue with the monitor
turned on.  I don't understand why they do not make it known to the
customers by printing the info in the form of release notes.

Thanks for your help.

Cheers,

Joe
