:)  this test measures speed of some programs, not "languages".
results are depends mainly on bundled libraries and RTS. by no means
it demonstrates speed of compiler-generated code of carefully-written
program what is typically considered as "language speed". the reasons

1) C++ people (and probably Fortran too) aren't so interested in
making fastest possible programs as Haskell community. it becomes
popular a few years ago, you can find that Haskell becomes several
faster at average since then, which doesn't reflect actual
improvements in GHC code generation (10-20%)

2) Most programs there depend on speed of libraries. Moreover, there
is limitation that it should be *bundled* libraries, so results
greatly depends on what currently included in one compiler or another

3) it's prohibited to write your own fast code if bundled library is
too slow (for example, because it's too general)
