recently there was a post on R-help/Rd ?? with this link on benchmarking
different 'number crunching packages'. They used a series of tests,
although I didn't check they used all the types you mentioned. I couldn't
find test code at first glance but myyebe it is available on request???

Recently I posted to this list with a question about using the Intel 10.1
compilers in building R and one response was basically, why in the heck
would you want to do that? The answer is that my sysadmin believes that
there will be a performance boost with the Intel vs. Gnu compilers on our
Linux cluster, of which I am one of many users. Wanting to be a good citizen
and use my machine time wisely, I'd of course like to use right tool to
build the most efficient installation of R and associated packages. BTW, we
got R to compile nicely using the settings at the end of this post.
Looking back on previous posts, however, it seems that there is no consensus
as to how to benchmark R. I realize such a task is not trivial, nor
controversial, but does anyone have a set of time-consuming tasks that can
be used to compare R installations? It would seem logical that such a
benchmark would include sub-benchmarks on file access, interpreted intensive
tasks, C intensive tasks, BLAS intensive tasks, etc. You developers know
more about this than I do, but I know enough to realize that there won't be
one simple answer. Nevertheless, I'd like to make my usage decisions on
something rather than anedotal claims.
So, does anyone know of a good benchmarking script or would be willing to
contribute one?
And here are the settings we used to compile R with Intel 10.1 compilers:
