Rhino now uses over 3GB Ram for a new empty file

Rhino Rhino for Mac
2

With just Rhino loaded (no file open), I show 413 MB used by Rhino.
If I open a new file using the default “small objects - millimeters” template, Rhino uses 687 MB.

How much memory does Rhino use when you make a new file using a default template?
