  I just ran some tests with my primitive execution profiler and here is
what I found;

  If you run a routine that does not make use of EXECLOAD you will find
a speed increase with the MODULE form of the same routine (Walltime,
VTIME/TTIME and SIO were all better).

  If your routine already is EXECLOADed, or EXECLOADs itself, then your
wall time will be slightly more for the MODULE version, but the
VTIME/TTIME is still better (though not quite as good as when the
routine wasn't EXECLOADed) and SIO appear equal.

  My two tests were 1) a one line EXEC that did Z=DIAG(8,'QUERY TIME')
and 2) my DOCMD XEDIT that parses each line of a file into words (DOCMD
* WORD NOP was the command I used while XEDITing a 1300+ line file).
Each test call each version of the routine 50 times and parsed out and
totaled and averaged the CP IND USER command (I did mention that it was
a primitive profiler, right?).

  For routines that are only called once there is probably no savings.
The MODULE is bigger than the original routine.  The source code is
plainly visible (not meant for security).

  You can make your routine into an IMMEDIATE command, sort of like HT
and such.
