Hello Our customer has been trialling Enterprise PL/1 4.4, with the intention of upgrading from their current compiler, PL/1 for MVS&VM. They have issues with performance, particularly with CICS programs, where the CPU time of a transaction is 3 times what it was with PL/1 for MVS&VM. We have a PMR open with IBM, who suggested the NORENT option, which did reduce the CPU to just double the old value. IBM are suggesting experimenting with these options, below. Does anybody have any experience of these and which can have most impact?
