Optimize mdrun

GROMACS version: 2023
GROMACS modification: No
Hi
I want to optimize mdrun in order to obtain the best performance on this system:
RYZEN 5 SIX CORE SIX THREADS
RTX 4070 12 GB GPU
How to launch an MD-Run with best performance ?
How many MPI Threads ?
Should I use only -nb gpu -bonded gpu or also other options ?
