I've never had any performance issues in R (or any other packages,
really) with Dirk Eddelbuettel's Quantian "live" CDs or DVDs, and they
run the whole OS -- not just the applications -- from a *compressed*
CD/DVD. The key on Linux is, I think, to have plenty of RAM for I/O
buffering in addition to what's required for your R datasets -- my
smallest machine is a 256 MB 933 MHz PIII. I can't comment on the
Windows kernel, though -- I do Linux performance engineering for a
living :).
