The zIIP doesn't have the full functionality of a CP, so it won't necessarily complete the same amount of work as fast as a CP could do it. However, if your site is not using the full speed of the machine then the zIIP, which runs at the full speed of the machine, could potentially do more work than the CP for a given amount of time. Something else to consider, though, is that there frequently isn't that much work for a zIIP to do -- unless your site is running Java and DB2 and Websphere and MQ Series in production, that is. We didn't have these products and it was rare for our zIIP to run more than 3% of the workload, so it was almost never very active.
