The CPE runs pipeline threads in parallel, not necessarily CAS processors. In a CPE descriptor, generally all non-CasConsumer components make up the pipeline.
Change the following line to indicate how many pipeline threads to run, and make sure the casPoolSize is number of threads +2. <casProcessors casPoolSize="2" processingUnitThreadCount="1"> Eddie On Mon, Apr 13, 2015 at 7:44 AM, Mario Gazzo <[email protected]> wrote: > It appears that I can only utilise a single CAS processor even if I > specify many more.
