your runtime heavily depends on the number of atoms in your system.
What I strongly recommend is reducing your system size as much as
possible (might require testing of different system but it depends
if its worth the time) usage of a GPU if available or at least a
cluster node with more than 8 cores (if available),
Equilibration time does not depend on production runtime.
Equilibration means you run such that the
temperature/volume/pressure/energy/density have settled down and
e.g. no major structural changes occur in your protein (RMSD) and
other quantities. All depending on the ensemble and your quantities
Though depending on your system maybe 10-100ps are enough of
equilibration, but maybe you even need a few ns.
