Java on System z

Interesting that Mr. Greiner states that Java is not a good workload for mainframes. I refer interested readers to the following reference:

http://www-03.ibm.com/systems/z/advantages/zaap/index.html

which describes the IBM zAAP, available on the System z mainframe. It uses one of the central processors (CPs) as a dedicated offload engine specifically for Java, XML and other application features. The use of these engines does not increase the license cost for zOS and they are priced lower than a full zOS CP.
