Efficiency low

GROMACS version: 2021
GROMACS modification: No

Hello GROMACS users,

Unfortunately I am having some trouble with the efficiency of my jobs. I am using two nodes and 16 cores for my job, but at the end of the job GROMACS states that the efficiency is 25% (it took a long time). Does somebody happen to know how to optimize the efficiency? Thank you in advance!!
