Selecting the high-performance option

The high-performance option (HPO) is for users whose top priority is to optimize terminal response times and maximize transaction throughput. HPO improves performance by reducing the transaction path length; that is, the number of instructions needed to service each request.

Note:
Use of HPO potentially allows CICS® application programs to bypass all MVS™ integrity controls. If you decide to use HPO, ensure that the application programs used on your CICS system meet your own installation’s integrity requirements.

The code to support the VTAM® authorized path feature of HPO (the improved path through VTAM) is in CICS.
