One of my co-workers is trying to improve the performance of an Enterprise 4.1 program that decomposes an input XML file into record fields for processing by later programs. The volume of the XML input has increased quite a bit and the performance may soon impact SLA's.
This program is currently compiled with XMLPARSE(COMPAT), so I advised him to try compiling a test version with XMLPARSE(XMLSS) and run some production data through both versions a few times to get some average performance numbers. The XMLSS version seems to be running about 10% more CPU utilization and elapsed time than the production version, on average. Are there any tweaks or adjustments that can or should be made to the XMLSS subsystem to improve performance? Our environment is z/OS V1 R12, z196 hardware. Any RTFM would be most appreciated, since I can't make any such changes myself but have to refer them to my systems programming group for consideration.
