No way! The licensing fees were a real issue, as every developer for YellowBox or OPENSTEP for Windows will confirm (the end customer was getting hurt by those fees there, the fee was the reason why the runtime of these frameworks for Windows was not free).

About the speed? I don't have any numbers to support my claim, but the Display PostScript is faster than Quartz. That will definitely change with future releases of OS X, but the DPS shipping with OPENSTEP/Rhapsody was highly optimized (10 years) and faster that you'd think.
