There are two questions embedded in this: How to work out where the CPU time is going. Whether compiled REXX will go faster.
On the first question I generally just use a say with the time function - but that just gives me ELAPSED time. Might be a good approach to searching for the culprit. On the second question, it really depends on how much time is spent in REXX code and how much time in the things it calls. In our case most of the time is in the things it's orchestrating so compiling never made much sense/difference.

I'm looking for a software (like STROBE, or IBM APA for Cobol or Db2 program) that can explain us where interpreted REXX CPU consumption is. We tried APA but it says IRX modules and i cannot map with source code. We tried EXECUTIL but it list the sequence of instruction, not the CPU part of it. Does it exist suche a software ? will it be better if i use Compiled Rexx ?
