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 :).
[The part omitted here said, supported by data, that other people did have performance issues. In particular the `slowest scenario' was not running from a CD, but a USB drive. Please do not remove the essential parts of other people's threads without indication -- it is discourteous to both poster and the reader.]
