Hi Folks, Sorry to raise what has probably been discussed before, but I an repeatedly struck by the comparative slowness of S-plus for Windows compared with R for Linux when doing much the same thing. I don't have a direct comparison, because they're not running on the same machine; but machine W has a faster CPU and more RAM than machine L, yet S-plus on W seems to take longer by quite a big factor (of the order of 5x) than R on L. My instincts say that "WIndows" is probably a significant factor in the comnparison, but still ... Ideally, to compare R with S-plus, one should look at them both on the same OS (Unix or Windows) on the same machine. Can anyone give me clean comparative speeds?

Given you do not link R against very specialized libraries such as ATLAS on one and not the other OS, I found no dramatic differences between R on Linux and Windows, but that might depend on the application as well.

You will find a speed comparison of S-PLUS and R, but also Matlab, Octave,
Scilab, Ox and O-Matrix under Windows at
http://www.sciviews.org/other/benchmark.htm. It seems that, at least under
Windows your impressions are confirmed. Also, I measured that R is a little
bit faster under Linux Mandrake 9 on the same computer. So, comparing S-PLUS
under Windows with R under Linux could be even better in favor of R.
However, I do not draw conclusions about Linux version of S-PLUS because I
never tried it.
Best,
Philippe

Subject: [R] Spedd: R vs S-plus
Hi Folks,
Sorry to raise what has probably been discussed before,
but I an repeatedly struck by the comparative slowness
of S-plus for Windows compared with R for Linux when doing
much the same thing.
I don't have a direct comparison, because they're not
running on the same machine; but machine W has a faster
CPU and more RAM than machine L, yet S-plus on W seems
to take longer by quite a big factor (of the order of 5x)
than R on L.
My instincts say that "WIndows" is probably a significant
factor in the comnparison, but still ...
Ideally, to compare R with S-plus, one should look at them
both on the same OS (Unix or Windows) on the same machine.
Can anyone give me clean comparative speeds?
With thanks,
Ted.

Anecdotal evidence has constructed a few scenarios where R will run, but S-PLUS won't, and a few where R will barely run, but S-plus has very few problems (problem == slowness, in this case). It would be critical to be a subjective Bayesian about it, since weighting of common applications, and perhaps more importantly, quality of code for matching up with the difference, will have a large impact. best, -tony -- A.J.

I well take the point that comparative speeds will depend on what you are doing -- indeed that is apparent from the benchmarks -- but there is still evidence that overall one can expect distinctly greater speed from R.
