in thread Subroutine overhead in Perl

We just used /usr/bin/time to measure the over all execution time:

$ time java -cp $CLASSPATH:. SudoKu d.txt $ time ./sudoku.pl <d.txt

    It has been a while since I have developed java code, but I think this means the java was already compiled, while the compile time was included in the perl.

      So? Aside that it's not entirely true — Java run-time engines typically compile Java bytecode into native code at run-time — it is not standard behaviour to run Java programs from their sources. Perl's developers made a choice to parse the source every time, and Java should not be penalized for it.

        I'm sorry: I was probably not clear. The timing for 'java' does not include the 'javac' step, but the perl timing includes the conversion of source to code for the interpreter. I was just suggesting that the 'time' commands were not timing the same things.
