This is pretty damn good, especially if you just want to do MD on the
structure.
Typically before starting MD you only need to do a few hundred steps or so
of minimisation to clean up the structure. See the tutorials for examples:

It is purely to remove bad contacts and stop your system blowing up because
hydrogens were placed in non-optimal positions. When you run the MD you will
be equilibrating the system so it quickly move out of the minima the
minimisation was heading towards.
All the best
