Dear MK,
I am sorry you haven't tested on a test system before or fully understood
the implications of your statements - especially when the need for
availability of the system is that big, but hey, that can happen to me too.
With regards to the 50% usage of your processors: perhaps there is
disk-contention (on unix: run a SAR report).
Good luck with your endeaours,
Best regards,
Erik
