How much of current R&D time is humans thinking, and how much is compiling projects, running computer simulations or doing physical experiments?

E.g. would having faster than human speed uploads, speed up getting results from the LHC by the ratio of their speed to us?

Also do you have some FLOPS per cubic centimeter estimations for nanocomputers? I looked at this briefly, and I couldn't find anything. It references a previous page that I can't find.
