 Nobody would believe benchmarks on the D web site. Heck, I
 don't believe any benchmarks published by the developers of
 any language.



When you publish the source code of the programs, and the compile and build
logs, and the compiler and linker versions, and the OS the measurements were
made on, ... others don't have to just "believe" because they can try to
confirm the measurements for themselves.

Which is why the benchmarks game measurement scripts markup source code and log
the build -

It's true, they can, but they don't. I have nearly 30 years of experience with
this.

I tend to assume that benchmarks posted by the developers of the
language are correct, but deliberately chosen to make the language look
good and the competition look bad.  Reproducing the tests locally would
only catch the most blatant forms of cheating.

Instead of this useless bikeshedding someone could provide the required 
help to Isaac here. I'm guessing he also accepts money and other kinds of 
gifts as a dedication of gratitude. I personally thank him now, the test 
has revealed many useful languages to me and I've found it very 
informative.

What some language distributions have done is they include the language 
shootout tests in the standard distribution. The language community can 
do all sorts of things to make the up to date test results a reality: up 
to date open source compiler for all required platforms, debian packages, 
help with the scripts to make the tests run and so on. The site is a 
great advertisement - I'm pretty sure the Go developers have realized 
that already.
