The only thing I'll add to what Ralph has said overnight here is that an awful lot will depend on your local config, so the best way to work it out is to do what we did and benchmark it yourself and see what happens for you with the code you care about. To paraphrase Winston Churchill: there are lies, damn lies and other peoples benchmarks.. ;-) Best of luck!
