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 insist on Linux, even if I have to create a secondary
partition and install Linux myself.
A friend installed Linux for me, but he has not been available to
answer all my questions. For that, Google has been quite helpful.
I installed Linux, because it offered more flexibility than I
could get with any version of Windows. For example, on my dual core
Vista machine, I can't run two Python sessions simultaneously. I'm
doing real time downloads and uploads with an FTP site. I was doing
those under Vista, but Windows could not be easily extended to multiple
applications like that in parallel without paying more for Windows
Server than I paid for the hardware. So far, I'm working fine with 2 GB
RAM under Linux with fewer problems than I have with 8 GB RAM under Vista.
Hope this helps.

time it would take me to migrate my entire system to Linux (including
a database that I access via an R package.)
It would help to know what is your system. A sessionInfo() would be a start.

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,
Brigid
