So under 100% equal conditions, EMS would always be faster since it doesn't require the memory contents to be copied to conventional before they can be read by DOS. But what about the somewhat uncommon case of EMS which is limited to 8-bit memory accesses to the page frame? (Due to the LA lines only having 128kB resolution and the page frame often sharing a 128kB region with a physical 8 bit device.)
Would 8 bit EMS still be faster on a 0 wait system? Twice as many bus cycles and added waits vs having to copy the XMS back to conventional (a 16 bit accessed 0 wait operation)
