RexxCPS benchmark results

This is a list of RexxCPS 2.1 results, showing the number of Rexx clauses per second observed on various combinations of hardware and operating systems.

A clause is the fundamental grouping of Rexx syntax; roughly, it is the unit of syntax that may exist independently on a single line without using semicolons or continuation characters.

These are all unverified, volunteered results, and should not be used as a basis for decision; they shall not be used for any commercial purpose.
