Just as a follow up to this issue, I converted a simple MR view from JavaScript to Erlang, which brought the View Rebuild time down from approx 8 Hours to 25 minutes.
Looking at "top" and "mpstat" it seems to use multiple cores/CPU's (although vmstat suggest it doesn't, which is confusing) A good tutorial on Erlang can be found at http://learnyousomeerlang.com/introduction#about-this-tutorial should anyone else have the need!
