Not my claim. The claim is here:

    http://shootout.alioth.debian.org/benchmark.php?test=all&lang=all&sort=fullcpu

I believe that this shootout is somewhat flawed in that the examples
are all relatively short pieces of code unlike anything that even
approaches real world code.

It should be noted that the benchmark attempts to use the technique
most approriate for the language. So, for the count words example,
the C++ version uses std::vector from of the STL:

    http://shootout.alioth.debian.org/benchmark.php?test=wc&lang=icpp&id=0&sort=fullcpu

while the C version uses standard C arrays:

    http://shootout.alioth.debian.org/benchmark.php?test=wc&lang=icc&id=0&sort=fullcpu

Are you surprised that C arrays are faster than std::vector?

"    Baldie is such a wonderful villain
The Linux/OSS community could not possibly ask for a better villain than
our man Baldie. He is absolutely perfect for the part. Just look at his
creds: 1) Physically repulsive; 2) Morally bankrupt; 3) Megalomaniacal;
4) Possessed of a truly nasty, abusive disposition; 5) Prone to Hitlerian
ranting; 6) Stalinesque paranoia... The list just goes on and on. The man
has the gift of true despicability, no doubt about it. If it weren't for
Baldie we'd be stuck with Bilgatus' merely vacuuous and creepy persona
for an anthropomorphization of the Evil Empire -- tepid at best."
