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"? -- Charles Brown charles@cv.hp.com or charles%hpcvca@hplabs.hp.com or hplabs!hpcvca!charles or "Hey you!" Not representing my employer.
