Running a compiled REXXCPS, I get these results: Run 1. Performance: 6587190 REXX clauses per second Run 2. Performance: 7755269 REXX clauses per second Run 3. Performance: 7560471 REXX clauses per second
This is on a lightly loaded z10 (Real CPU ID = 000sssss20978000). The numbers appear to vary directly with the CPU Busy values. The LPAR shares its 5 CPs with two other lightly loaded LPARs that are capped, with very low ceilings. If I run the uncompiled version, the result is approximately 25% of the compiled version's. I haven't had a chance to try it in one of the IFL LPARs. It is tough finding a time when they are not extremely busy.
