And here are the shootout benchmark results: -------------------------------------------------------------------------------- Program Size Allocs Runtime Elapsed TotalMem -------------------------------------------------------------------------------- binary-trees -6.4% +0.0% -2.4% +0.0% -7.4% fannkuch-redux -0.8% +0.0% -3.6% -3.6% +0.0% fasta -0.8% +0.0% -4.8% -0.6% +0.0% n-body -6.2% -0.0% +28.5% +29.4% +0.0% pidigits -0.8% +0.0% -2.9% +2.9% +0.0% spectral-norm -6.3% -13.9% -0.0% -0.0% +0.0% -------------------------------------------------------------------------------- Min -6.4% -13.9% -4.8% -3.6% -7.4% Max -0.8% +0.0% +28.5% +29.4% +0.0% Geometric Mean -3.6% -2.5% +1.9% +4.2% -1.3% It might be worth looking into why n-body is 28% slower. P.S. I've now enabled the shootout benchmarks in nofib by default, as they're pretty quick to run and run on any machine. -- Johan
