One thing that Linux makes trivially easy is to interpolate R with C++

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 tweaks...
Oh, come on: you admit don't know what you are talking about, but you
then give advice on something unrelated to the command line. That
forces other people to correct your erroneous advice for the record.
You do not need Rcpp to use C++ with R, and only a very small minority
of C++-using packages do whereas Rcpp leans very heavily on the work
of the core team to support C++.
There is a C++ compiler which is part of the Rtools collection which
you need to use compiled code on Windows. But actually that is no
different from Linux, where the person who installed Linux has to
arrange to install the compilers from the distro.

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 migrate my entire system to Linux (including
a database that I access via an R package.)
I don't know how much it matters what R is doing - but I've got R
pulling a large amount data from a database, performing many complex
computations on that data, and then writing output data to a database.
Thanks so much for the input,
