I've never used C or C++ so I probably don't mix with
enough of those guys to say, but the impression I got
was of, shall we say, 'assertive confidence'.

See the FAQ "How did you measure
?"

So look at the tasks where the fastest program takes
seconds and needs more than 5 lines of code :-)

That's been shown for Gentoo/Intel since at least

Contribute elegant slower programs and maybe we'll
show them - we're currently showing two C++ sum-file
programs, one's ~25x faster than the other.
