It would be the same, but not in the way you are thinking.
		Sun (DPVM)	Amiga (no DPVM)		Amiga (with DPVM)*
All software
fits into	  FAST		  FAST			  FAST
physical RAM

Doesn't fit into
physical RAM	  SLOW		Does not run at all!	  SLOW
------------------------------------------------------------------------
Note *
  The Amiga does not have DPVM (Demand Paged Virtual Memory) so this
  last case is hypothetical.

  Please carefully study this chart before deciding whether DPVM makes
  sense in a small computer.  Which would you rather have, "SLOW" or
  "Does not run at all"?
