I updated the comparison chart with another simulation that uses the Verlet cutoff scheme:
It might be too early to tell, but I’d say that there is no significant difference between using the Verlet and the group scheme in Gromacs 4.6.5 — they both give an area per lipid that too low (compared to results obtained with Gromacs 4.0.7). Using the Verlet scheme is about two times slower in performance than using the group cutoff scheme.
