A 386 is just plain slower than a 486, even at the same clock speed.
Intel did a lot of profiling and made the most commonly-executed
instructions faster (and slowed some uncommon ones down). I've heard of
compile times in the weeks on modern kernels. I haven't tried it on Irving
yet, but from compiling a few toy programs I wouldn't be surprised...

Well, considering that linux-8086 can't compile *anything* yet by itself,
Andy's actually slightly ahead. :->
