Put these as the last two lines of your program:

    BEGIN { warn sprintf "after compilation: %.2f %.2f\n", times }
    END { warn sprintf "after execution: %.2f %.2f\n", times }

That's the user/system cpu time (in seconds) after compilation and
after execution.

I bet if your program is of any significant size and purpose, the
compilation time will be a very small fraction of the execution time.
Now think of how much *human* time you'll be spending keeping a
"binary" up to date, and also realize that the time to load an
entirely separate unshared binary will probably be more than the time
for the already memory-paged-in Perl executable (on most systems :) to
simply read the source and compile it.

In short, Perl's compilation time is nearly always not the issue, once
you look at it.
