> 100x speed improvement ... Vs. Ken's Blog says "up to 100 times", and Wikipedia gives a lower estimate. Theory: Your 100X experience compared Intel's "exact emulation" code (noted in the article) with native x87. That emulation would have to cover the myriad x87 oddities and corner cases which Ken describes. Vs. Ken's & Wikipedia's are comparing x87 to various "good enough" 8088 floating point libraries - so naturally much faster than Intel's exact code. (And yes, speed might have been a low priority for the team writing Intel's emulator.)
