Doesn't the example in the benchmark show performance problems in EXECIO instead
of REXX? EXECIO, IMO, is not part of the REXX interpreter, but instead it is a
vehicle (an external function) to do I/O from REXX on z/OS. Other REXX
implementations (for example, on Linux or Windows) don't use EXECIO etc.; I/O
there is done with native REXX functions.

So to be fair, the REXX interpreter functions should be compared with Lua
interpreter functions, for example: some loop control or arithmetic. Compiled
languages like C will always outperform interpreted languages in this area, so
such comparisons are only of academic interest.

Kind regards
