To try to answer the actual question I run x86_64 Linux and both 32-bit Windows XP and x64 Windows 7 on my home desktop. So from years of experience of using the same hardware on those OSes: 1) Generally Linux will be a bit faster, mainly because I do not hobble it with

[R] Performance Difference? Windows vs. Linux

2011-03-18 Thread Brigid Mooney
I'm not trying to start a Windows vs. Linux debate, but I've been using R on a Windows machine for a while, and was recently wondering if R's performance would be faster on a Linux machine. And similarly, if any incremental increase in processing speed would be worth the time it would take me to

Hi Brigid, I haven't used it yet, but I would suggest profiling your code with 'Rprof' on both a Windows and Linux machine. ?Rprof for details. Hope this helps, ~Caitlin On Fri, Mar 18, 2011 at 3:00 PM, Brigid Mooney bkmoo...@gmail.com wrote: I'm not trying to start a Windows vs. Linux

Others can discuss the comparative speed. I recently installed Linux on a new quad core computer I purchased. I found it surprisingly easy to learn how to do the things I needed. Now the hard drive is dying on my Vista notebook computer. In shopping for a replacement, I likely will

One thing that Linux makes trivially easy is to interpolate R with C++ through the Rcpp package. The GCC compiler collection is part of all mainstream Linux distro. This is, however, not the case with Windows: you may be able to do it eventually (not sure about this point), but it takes quite some
