I think a neutron star would have time dilation below 2x. Would be interesting at our time scale, but on the order of magnitude we're discussing of the increased chemical speed i think it would just be noise.

A neutron star is right on the edge of being a black hole, which has infinite time dilation. A neutron star should have very very high time dilation.

There is a big difference between infinite and very high gravity. Neutron stars have only about 50% time dilation on the surface, as the surface is at about 50% their Schwarzschild radius.

Don’t you mean 100%? From what I can tell, the radius of a neutron star is about twice its Schwarzschild radius.

So...50%?
