R help - Jun 2009 - How to get best performance from R on Linux?

Hi

following a discussion on difference in speed of R between R and Linux, I am
wondering: is there a howto to get the most (concerning speed) out of R? I
am not talking about vectorisation and techniques in doing the analysis, but
what should I look at when I want to get "the fastest R" on my
computer -
compiling myself? specific switches? compile libraries?, ...

Thanks

Rainer

Did you look at R Admin manual and its Appendix B on Unix configuration?

And the end of the day, it will most likely depend on exactly what it is you
are trying to do, so you get back to square one and the need to profile,
benchmark, ...
