in reply to No More Meaningless Benchmarks!
Hah, that's hilarious. I thought much the same thing when I saw the benchmark after having seen what perl did internally.
If you're convinced that something is making an actual difference, run the benchmark a few hundred times (should be quick on a tiny proof of concept program) and do some stats on the results (average and standard deviation especally). This will help show if what you're doing is actually changing anything.
