If you need to ramp up your ZIIP usage, DB2 V10 may be riding to your rescue. IBM is currently warning customers that over-using ZIIPs may lead to serious performance problems because of the way z/OS manages them vs. the way it manages general purpose CPs. You can't be too rich, too thin, or too ZIIPped.
