[gmx-users] the code speed between Gromacs 3.0 and Gromacs 4.0

[Dechang Li]

Dear gmx-users, 

	Are there any comparisons of the code speed between Gromacs 3.0 and Gromacs 4.0. In my calculation, I got a speed about 3.5ns/day of a system have about 50,000 atoms, using 8 CPUs with Gromacs 3.3.1. In contrast, the speed can reach up to 7.3ns/day when switch to Gromacs 4.0.7 while the other conditions are keep the same. Is this result normal? 



Best regards,
