For quite some time now I have wondered the speed of different modes and which is the most efficient. First of all, is 32-bit any faster than 16-bit assembly (assuming you have the same system. Also, is there any more speed that can be gained from using real more segmented model, or does real and protected mode flat work the same, but with less complications. I wondered if the extra versatility of the segment registers would allow more effecient code. Please specify the difference of efficeincy in machine cycles of possible
