Thank you for your answer. I didn't realize a system like this is already in the "lot of water"-regime (it makes sense though, ~95% of the particles is water). I could lower the water content a bit by reducing the solute to box distance (eg from 1.5 to 1.2/1.0nm), but that only saves a few percent. In practice it will mean that for any system containing soluble proteins, the group scheme will still be faster? Right?
