The best benchmark is a calculation you really want to do. For most people matrix algebra is an insignificant proportion of what they do in R. A few need complex matrix arithmetic (where compilers and BLAS differ a lot in speed). So there is no universal benchmark. Also, the reference BLAS su

Hi All, I've just rebuild the latest R with the Goto BLAS on our new Intel quad core machines. I did a few basic matrix calculations, and I was very impressed by the performance I saw. I wonder if anyone has a more rigorous benchmarking program for R. I downloaded a old R test/benchmarking pro
