This is a function of the 386 chip, not Windows. The 386, in protected mode, takes *significantly* longer than real mode to load segment references (because they have to go through a page table and they might page fault). That is why it is so important to try to use near pointers wherever possible, which makes programmer's lives significantly more confusing than using 32 bit pointers everywhere.
