Re^5: Best way to sum an array?

Darned if I can find any significant difference for as few as 3 numbers to add. Pretty consistently 4-5/100ths for both to start perl, count the numbers and return to the prompt

Interesting. Using precisely your 2 scripts, I see the withListUtil.pl taking about 60-70% longer.

$ time for i in {1..1000}; do perl withListUtil.pl > /dev/null; done

real    0m6.512s
user    0m3.820s
sys    0m2.867s
$ time for i in {1..1000}; do perl withoutListUtil.pl > /dev/null; don
+e

real    0m3.880s
user    0m1.538s
sys    0m2.497s

For the record, this is perl v5.20.3 with List::Util v1.42 on 64-bit Linux.

I guess my point (in my reply to you), is that if the cost of loading a (small, mostly precompiled binary) module is a significant factor in the runtime of a given application, then Perl is probably the wrong choice of language. But really, the "why wouldn't you" in the post to which you replied was a throw away comment rather than a scientific pronouncement; you seem to be making an issue of a non-issue. S'funny, I'm normally on the other side of this discussion. I rarely advocate the use of a module over one line of perl; but in this case, the benefits equation really does bias one way in 99% of cases. But I guess I'll go back to lurking... With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
