The structure of the Milky Way

This article reminds me a lot of the book "A Fire upon the Deep" by Vernor Vinge.

While reading this article and viewing the diagram of the Milky Way, I wondered, does time pass more slowly from the point of view of those bodies near the center of the galaxy, which are moving more quickly?

Of course the faster you go the slower time passes but you have to travel at least 30% the speed of light to make a dramatic difference. See the table here:

Also: the star with the shortest known period orbiting our central black hole travels no faster than 1% the speed of light.

Peak stellar speed observed as "nearly 3% the speed of light":

which appears to be rounded up from actual 2.55% value:
