Just to complement:

My input is a water-tight 120,000 vertices mesh.

I have tried that plugin.

Problem is it takes over 2 minutes in Release in order to at least maintain the vertices resolution (I don't care about feature loss).

What am I missing?

There is a plugin in the Polyhedron demo that allows you to mesh the
offset surface of a given input mesh. The quality of the result depends
on the input criteria. It will generate a non-self-intersecting surface
but sharp feature that should be in the output mesh will not be present.

It handle positive and negative offsets.

The code of the plugin is here:
